Xhr failed visual studio code ошибка как исправить

Do you want to fix XHR Failed error in VSCode?

At its heart, VSCode is based on the Electron framework. That means VSCode is basically a Chromium with code editing features developed on top of it. Whenever you get an error from VSCode, it’s most likely Chromium errors.

Users have reported that when they try to install an extension, especially behind a proxy network, they are presented with XHR Failed error. XHR Failed indicates that a few XHR requests may have been failed or interrupted while VSCode sends and receives extension information from the server.

In this article, we will discuss about possible fix for XHR Failed error in VSCode.

Use a direct internet connection

If you’re behind a proxy network, try to disable it if you can.

Most of the time, the proxy network includes a firewall that may block VSCode requests to its servers.

In rare cases, the proxy network supports only HTTP or HTTPS protocol, leaving other communication through its network blocked, which can causes strange behavior in VSCode.

You can follow the instructions from Microsoft Forum to disable proxy on Windows 10. macOS users can consult this guide to do just that. Linux users should be able to disable proxy on their own, given that they are often more tech-savvy, but here’s a few tips on how to turn off proxy in Linux anyway.

Turn on automatic proxy detection

Chromium uses system proxy settings by default, so there’s a chance VSCode’s Chromium core does not recognize the proxy and cannot send/receive network data.

In order to turn on automatic proxy detection on Windows 10, follow HowToGeek guide.

Ignore certificate errors in VSCode

The actual implementation of the corporate proxy can vary from organization to organization, but there is one thing in common : they could all cause certificate errors.

Secure websites and applications use their own certificate to prevent themselves from online attacks. Internet traffic going through a corporate proxy can be modified by the proxy network in real time, causing certificate irregularities. Some other times, your organization offers their own CA certificate, which makes the situation even more complex.

You can try launching VSCode with --ignore-certificate-errors flag to disable strict certificate checking.

On Windows, the easiest way to do this is by running code.exe --ignore-certificate-errors from a Command Prompt window.

On Linux and macOS, you have to open Terminal app and run code --ignore-certificate-errors.

After that, try installing the extensions again to see whether the error message goes away.

Disable JS source maps

Source maps is basically a JavaScript engine feature that maps a combined/minified file back to an unbuilt state (think unminify). It was made for easier JavaScript debugging, but we don’t need to debug VSCode itself, so disabling it is safe. Plus, users have reported that disabling JavaScript source maps and CSS source maps solves XHR Failed error message .

In order to disable JavaScript source maps and CSS source maps in VSCode, fire up Command Palette and search for Developer: Toggle Shared Process.

On Developer Tools that just pops up, click the Gear button (settings button) in the upper right corner.

Uncheck Enable JavaScript source maps and Enable CSS source maps, then close the window.

Change your DNS

If you live in a country where heavy internet censorship is implemented, such as China, Egypt or Turkey, maybe the firewall has blocked some Microsoft servers. You can try setting your DNS to Google DNS (8.8.8.8) or Cloudflare’s 1.1.1.1 servers to see if XHR Failed happens again or not. On Windows, you may have to run ipconfig /flushdns to flush the system’s DNS cache before changing the DNS.

On Linux machines, you have to edit /etc/resolvconf/resolv.conf.d/base to make DNS changes persistent through restarts. Add these two lines to the file before rebooting so that the changes take effect.

nameserver 1.1.1.1
nameserver 1.0.0.1

Install the extension offline using VSIX file

All VSCode extensions is now available in the form of VSIX-packaged files. This allows for offline installation as well as extensions which are not originated from VSCode Marketplace.

You can download VSIX files directly from VSCode Marketplace or Open VSX Registry and install it offline, without the need for an internet connection. See our guide on How to install extensions in VSCode for detailed installation steps.

Vscode: XHR Failed on trying to install plugins via Visual Studio code

Report Issues to prefill these. —>

• VSCode Version: 1.16.0
• OS Version: Windows 10

Steps to Reproduce:

1. When trying to install a plugin, i get an error XHR Failed.
2. Also when i try to download the extensions manually and try to install it via the options «install from VSIX», it fails silently.
3. I am behind a proxy network.

i got same problem and solved it by doing that

1. Go to : Control PanelNetwork and InternetNetwork Connections
2. Choose your connection network and ( right click on it then choose properties )
3. Select » Internet Protocol Version 4 (TCP/IPv4) and then click on properties in the bottom of this section
4. At General section click on » Use the following DNS Server address : «
5. Make » Preferred DNS server : 8.8.8.8 «
6. Make » Alternate DNS server : 8.8.4.4 «
7. Restart VS code

I have also encountered this problem.
v1.16.1, win7, http_proxy, 32bit or 64bit

If you open the Developer Tools, can you find anything interesting there?

If you open the Shared Process window ( F1 , Shared Process ), is there anything interesting in those Developer Tools?

XHR failed: : Error: XHR failed: , at XMLHttpRequest.t.xhrRequest.r.TPromise.t.onerror (file:///C:/Program Files (x86)/Microsoft VS Code/resources/app/out/vs/code/electron-browser/sharedProcessMain.js:4:242078)

In the built in developer tools, i get the above error message when i try to install any plugin.

Screenshot below:

I was having this same issue yesterday with every plugin I tried (after a fresh installation of VS Code). Today, with no changes, I am not running into the issue and am able to install plugins. Did something change on the server side?

Version 1.16.0
Commit 787b31c0474e6165390b5a5989c9619e3e16f953
Date 2017-09-06T16:19:37.192Z
Shell 1.7.3
Renderer 58.0.3029.110
Node 7.9.0

OS: Fedora 26

@vinothbabu @dsneddon Check the Developer Tools Network tab, any interesting clue in there?

@modigrv Did something in the service change in the last few days?

@joaomoreno There hasn’t been any change in this area. Also, last deployment was on Wednesday, 13th Sept, nothing changed on server after that.

@joaomoreno I don’t see anything interesting in network tab, while trying to install the plugin.

@vinothbabu Did you check the Shared Process’ Network tab?

I open the Developer Tools Network tab and close it. And it is ok .
it’s wired！

Same problem here when I run VSCode without administrator permissions and try to search for a plugin

Developer Tools Console Log: -1505940233067.log.txt

Also getting this problem. Running VSCode on macOS 10.12.

XHR failed: : Error: XHR failed: , at XMLHttpRequest.t.xhrRequest.r.TPromise.t.onerror (file:///Applications/Visual Studio Code.app/Contents/Resources/app/out/vs/code/electron-browser/sharedProcessMain.js:4:242078)

My Network tab in the Developer Tools is empty after trying to install an extension. Just the error in the Console tab.

I got the same issue on Ubuntu14.04 with code 1.16.1 (behind a proxy), but i cannot find an error in the developer view.

Same issue, but not behind a proxy.

@jrieken Have you seen XHR Failed before?

No, maybe this is because of resource filtering/blocking @mjbvz added

The content security policy rules general should produce an error message that explicitly states that content has been blocked by the content security policy. #30850 has an example of those failures.

@vinothbabu / @KUGA2 Is the proxy http or https?

In my case, I couldn’t load extensions when I was behind a hotel proxy, but when I returned back to my network (where there is NAT but no proxy), it worked just fine.

I know there is at least one person saying that they are getting this error when not behind a proxy, but it does seem like being behind a proxy might be a common theme.

Strangely, I was getting this error when using my mifi device (I’ve never had the issue previously with previous versions VS Code).

At home on wifi and wired it seems to be working. Hmmn.

I’d agree with the proxy comment I guess, although the mifi bit is definitely weird.

@mjbvz it is a http proxy. And:

I also found a log now. Maybe this can help you figure this out

i got a solution 👍
go to network proxy setting and turn on «automatic detect» proxy and done

Same error here. js debug window shows nothing. sometimes error disappear after code restart, sometimes persist for days.

Linux, code 1.16.1-1505406497, http proxy (necessary, because of the corporate policy).

proxy log shows no traffic when code should get the extension info.

Today my code on Windows updated, now i get the same error as in my Ubuntu box.
@raj457036 Where is «network proxy setting»?

Windows 10

Go to start menu

Search for network proxy

Click on network proxy setting
Then select automatic proxy detection

Windows 7 -> 8.1
Open network settings
Click on lan settings
Select automatic proxy
And click apply/ok

Done restart code and everything will run fine

Check for the firewall and network access permission to code

Running Windows 10. My proxy settings are set to automatic. Still getting this error.

I’ve tried both the stable build and the insiders build. same error on both.

Same issue behind a proxy with code ver 1.17 x64 on win7. But with 1.14 (x86) all is fine.
Tried automatic proxy detecting, but the issue persists.
Nothing appeared on the Developer Tools Network tab when the issue arises.

same issue, behind http proxy
OS Version: Ubuntu 14.04
code —version
1.17.0
be377c0faf7574a59f84940f593a6849f12e4de7

I did some tests

1. OK with the parameter —proxy-server=x.x.x.x:xxxx
2. OK with gsettings proxies
3. Doesn’t work with environment variable http_proxy

Same problem behind a proxy,doesn’t have in previous version.

I’m seeing this, too. I’m using Windows Server 2008 R2, behind a corporate PAC file proxy.

I know VS Code can get to the internet because it was able to download the v1.17.2 installer. However, when doing an XHR connection to the extensions gallery, I get the XHR Failed error, with these errors in the dev tools console:

I think (in my case) it’s because VS Code sends a different User Agent header when connecting to the extensions marketplace. When downloading updates it’s Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Code/1.17.2 Chrome/58.0.3029.110 Electron/1.7.7 Safari/537.36 , but when getting extensions it’s sending VSCode 1.17.2 — and our proxy doesn’t let that through.

Update: When I use Fiddler to change the user agent to Chrome (Win), VSCode can reach the marketplace and install extensions without issue. Should Extensions be using a different user agent to the update checker?

FYI, I am still seeing this issue on Ubuntu 16.04LTS with 1.17.2 and I am not behind a proxy. I cannot for the life of me find the issue, but I did come across this little tidbit:

It will also note that the check for updates menu seems to just hang as if the application has no access to the interwebs. Everything else on my workstation connects just fine and has for some time now.

windows7/vscode 1.7.2 same problem, used a proxy

Still seeing this issue, but came up with a work-around on Ubuntu 16.04LTS based on the following thread:
https://github.com/Microsoft/vscode/issues/22214

Simply modify the Exec value in /usr/share/applications/code.desktop to:

Exec=/usr/share/code/code —unity-launch —ignore-certificate-errors %F

Finally seeing the list of extensions!

My workstation : CentOS Linux release 7.4.1708 (Core)
I add Exec=/usr/share/code/code —unity-launch —ignore-certificate-errors %F in file code.desktop
No work 🙁
code -version 1.17.2

• VSCode Version: Code 1.17.2 (b813d12980308015bcd2b3a2f6efa5c810c33ba5, 2017-10-16T13:57:00.652Z)

Any solution for Mac? I’m seeing ERR_NAME_NOT_RESOLVED in the console.

Getting the same issue on CentOS with the latest vscode release. I work in an offline environment and did not have these issues with the previous releases.

As soon as you click the Extensions tab you get «XHR failed:» and a blank extensions window, even though stuff could already be installed. Closing and re-opening the tab then show the installed extensions.

Developer Tools show:

Failed to load resource: net::ERR_NAME_NOT_RESOLVED marketplace.visualstudio.com/.
XHR failed: : Error: XHR failed: at XMLHttpRequest.t.xhrRequest.n.TPromise.t.onerror (file:///usr/share/code/resources/.

CentOS 7 behind a corporate proxy, same problem. Would be really nice to get some workaround.

Same Problem. Tried x86 & x64 build same issue.

• System: Windows 10
• Behind corporate proxy

I installed 1.18 today.
Same issue! (Ubuntu 16.04 in VM behinde proxy)
Win 7 Native, behinde proxy works

Before i installed the 1.18, i can install extentions without specifying the proxy settings. However, after i specified the proxy settings and installed the 1.18 version, i start to receive XHR failed warnings when i attempt to search for extensions, no matter whether i have specified the proxy settings.
It’s strongly suspicious that something changed in 1.18 version.

The same! (Win7 x64, VSCode 1.18)
— Temp Solution —-
But off the record, you can just open the *.vsix file by using Winzip or WinRAR, and simply extract the «extension» folder and drop it into your «SYSTEM_DRIVE:USERS\.vscodeextensions» folder, done! Then you just refresh (like Show Installed Extensions) and reload it in the extension-view if your vscode is openning.

I also can not install plugin with XHRfailed.And i open Develop tools and select Network tab just see

And i try to open https://marketplace.visualstudio.com/VSCode in the chrome,i can not open this page.I can open other page normally.

I also encounter this issue when trying to install plugins offline

I am also seeing the same issue with lubuntu and VSC version 1.19 latest one.

It seems like 1.19 fixed the problem for me, but the Powershell extension is currently broken as it attempts to connect to the internet during offline installation. @AkashEMC is it failing only on the Powershell extension or is it everything else too?

FWIW I installed 1.19 hoping for a fix, no luck.

Based on an earlier comment I read in this thread, I next ran code under sudo, got the warning «this is a really bad idea plus you are going to need to set the user directory», did so, and found that the problem goes away — extensions are browseable and loadable just fine.

i try to install an extention of chrome but i recieve a message XHR failed and am using Window 10

@Joebass12 hello , I met the same problem. Have you solved it?
My system is also win10, and vscode was downloaded yesterday.
I just want to download a plugin that the HTML file opens in the browser.

@Greyze I am behind proxy, with VSC 1.19 version on Lubuntu and not able to install any extension, and i tried all the available hacks available on internet/google.

This is still an issue.
I cant install plugins. I’m new to coding, I was looking forward to VS Code for web developing.
I’m using Atom now.
Really wish this issue would be resolved soon.
This link wont even open in my browser.
https://marketplace.visualstudio.com/VSCode

• VS version 1.19.1
• OS win 7 64 bit

I catch the same error.

But I try to use VSC version 1.17 and it works.

Windows 10 64 bit creators update, fully updated same error with 1.19.2

Reverting to another editor, will check back when VSC is more developed.

Same Issue, how I can fix it.

Just trying Visual Studio Code for the first time. Same problem. Cannot install extensions. XHR Failed. Was looking to suggest this as a tool for some users to write their own scripts, but since I can’t even get it to work myself I can’t really suggest it to our users. Guess I’m looking for a different tool. (Using Windows 10 creators update and version 1.19.2).

EDIT: Could have been a local network setting; seem to be able to connect now.

Is there no solution in sight?

I have being experiencing this since I can remember.

Using Win10
VStudio version 1.18.1
🔩

I solved this issue uninstalling every ‘Microsoft visual c++ redistributable’ files that I had on my computer, uninstalling Visual Studio Code and installing it again.
I hope this can help you

Troubleshoot : XHR Failed on VSCode

Do you want to fix XHR Failed error in VSCode?

At its heart, VSCode is based on the Electron framework. That means VSCode is basically a Chromium with code editing features developed on top of it. Whenever you get an error from VSCode, it’s most likely Chromium errors.

Users have reported that when they try to install an extension, especially behind a proxy network, they are presented with XHR Failed error. XHR Failed indicates that a few XHR requests may have been failed or interrupted while VSCode sends and receives extension information from the server.

In this article, we will discuss about possible fix for XHR Failed error in VSCode.

Use a direct internet connection

If you’re behind a proxy network, try to disable it if you can.

Most of the time, the proxy network includes a firewall that may block VSCode requests to its servers.

In rare cases, the proxy network supports only HTTP or HTTPS protocol, leaving other communication through its network blocked, which can causes strange behavior in VSCode.

You can follow the instructions from Microsoft Forum to disable proxy on Windows 10. macOS users can consult this guide to do just that. Linux users should be able to disable proxy on their own, given that they are often more tech-savvy, but here’s a few tips on how to turn off proxy in Linux anyway.

Turn on automatic proxy detection

Chromium uses system proxy settings by default, so there’s a chance VSCode’s Chromium core does not recognize the proxy and cannot send/receive network data.

In order to turn on automatic proxy detection on Windows 10, follow HowToGeek guide.

Ignore certificate errors in VSCode

The actual implementation of the corporate proxy can vary from organization to organization, but there is one thing in common : they could all cause certificate errors.

Secure websites and applications use their own certificate to prevent themselves from online attacks. Internet traffic going through a corporate proxy can be modified by the proxy network in real time, causing certificate irregularities. Some other times, your organization offers their own CA certificate, which makes the situation even more complex.

You can try launching VSCode with —ignore-certificate-errors flag to disable strict certificate checking.

On Windows, the easiest way to do this is by running code.exe —ignore-certificate-errors from a Command Prompt window.

On Linux and macOS, you have to open Terminal app and run code —ignore-certificate-errors .

After that, try installing the extensions again to see whether the error message goes away.

Disable JS source maps

Source maps is basically a JavaScript engine feature that maps a combined/minified file back to an unbuilt state (think unminify). It was made for easier JavaScript debugging, but we don’t need to debug VSCode itself, so disabling it is safe. Plus, users have reported that disabling JavaScript source maps and CSS source maps solves XHR Failed error message .

In order to disable JavaScript source maps and CSS source maps in VSCode, fire up Command Palette and search for Developer: Toggle Shared Process.

On Developer Tools that just pops up, click the Gear button (settings button) in the upper right corner.

Uncheck Enable JavaScript source maps and Enable CSS source maps, then close the window.

Change your DNS

If you live in a country where heavy internet censorship is implemented, such as China, Egypt or Turkey, maybe the firewall has blocked some Microsoft servers. You can try setting your DNS to Google DNS (8.8.8.8) or Cloudflare’s 1.1.1.1 servers to see if XHR Failed happens again or not. On Windows, you may have to run ipconfig /flushdns to flush the system’s DNS cache before changing the DNS.

On Linux machines, you have to edit /etc/resolvconf/resolv.conf.d/base to make DNS changes persistent through restarts. Add these two lines to the file before rebooting so that the changes take effect.

Install the extension offline using VSIX file

All VSCode extensions is now available in the form of VSIX-packaged files. This allows for offline installation as well as extensions which are not originated from VSCode Marketplace.

You can download VSIX files directly from VSCode Marketplace or Open VSX Registry and install it offline, without the need for an internet connection. See our guide on How to install extensions in VSCode for detailed installation steps.

We hope that this article helps you solve the XHR Failed error in VSCode. VSCode is an awesome code editor, equipped with numerous features that supports developers. Here’s a few of them that we’ve covered, if you’re interested :

Visual Studio Code — error «XHR failed» in extensions

After fresh installation of Visual Studio Code I decided install Python extension, but faced with an error «Unable to open ‘Extension: Python’: XHR failed.».

I don’t use proxy, but I use custom hosts file and firewall.

Process monitor shows that Visual Studio Code (code.exe) read the hosts file while starting, but when the file was empty the issues still exist.

I found nothing in Visual Studio Code logs «%AppData%Codelogs».

Than I looked into Windows Firewall logs (which must first be turned on) and found the source of the issue — Firewall bloked connections to «68.232.34.200». After disabling relevant rules the issue is gone.

The 68.232.34.200 was blocked by rules that should prevent sending telemetry to Microsoft.

So, if you are faced with «XHR failed» issue, check network requirements, hosts file and firewall rules.

Как исправить ошибку CORS?

В локальной сети между машинами, а также на одной машине в режиме отладки, делаю POST запросы XMLHttpRequest для выгрузки файла на второй сервер.

Со страницы https://xxx (, где ключи и сертификат самоподписанные (уровня 1). Тестовый сервер Nginx, в продакшене будет другой, но там такие же ошибки.)

на сервер https://upserver:8888 (, где ключи и сертификаты самоподписанные (уровня 2, с использованием собственного центра сертификации, корневых, промежуточных и конечных сертификатов) На порту 8888 работает Cowboy (Erlang/OTP v.23). Код с заголовками показан ниже.) Пока, там нет авторизации, а кросс-доменные запросы разрешены для всех (*).

Оба домена прописаны в hosts. В продакшене будут прописаны в DNS. Разрешения CORS установлены на обоих серверах, код показан ниже.

При первом открытии index.html на обоих серверах в браузере Chrome получаю ошибку сертификата, но после разрешения ресурса, страница открывается и далее работает. Хотелось бы чтобы она открывалась без этой ошибки и необходимости разрешения.

При загрузке файла на второй сервер в логе браузера (вкладка console) получаю следующие ошибки

Но файл успешно загружается на сервер. Не могу понять, что ему еще надо, и как исправить эту CORS ошибку?

Код заголовков на upserver:8888

Код запроса на клиенте

На стороне первого сервера https://xxx в конфигурации сайта под Nginx прописана следующая конфигурация

Вроде бы, везде всё настроено белее менее правильно, но ошибки мне очень не нравятся. Хотелось бы разобраться, что не так, и избавиться от ошибок.

Host domain.com
HostName domain.com
User USERNAME
ForwardAgent yes

1. Press F1, Press Enter on «Remote-SSH: Connect to Host. «, then enter on «domain.com». A new VSCode window is opened. In the new window, enter on «Linux» then enter the ssh password. On the bottomright, it says «Setting up SSH Host domain.com (details) Initializing VS Code Server». I press «detail», it gives some log which I put as the attachment vscode_remote_log.txt (Actual hostname and username concealed).
   After a while, I get a error dialog «Could not establish connection to domain.com. XHR failed»

Does this issue occur when you try this locally?: Yes
Does this issue occur when you try this locally and all extensions are disabled?: All other extensions disabled except «Remote — SSH»

Currently I cannot provide /etc/ssh/sshd_config because it is readable by root only. If needed, I can get it by contacting the system admin.
