Visual Studio Code "Error while fetching extensions. XHR failed"

This problem started a few weeks ago, when I started using NordVPN on my laptop. When I try to search for an extension and even when trying to download through the marketplace I get this error:

EDIT: Just noticed another thing that might indicate to what's causing the issue. When I open VSCode and go to developer tools I get this error messege (before even doing anything):

"(node:19368) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.(Use Code --trace-deprecation ... to show where the warning was created)"

The only partial solution I found so far was to manually download and install extensions.

I've checked similar question here and in other places online, but I didn't find a way to fix this. So far I've tried:

Flushing my DNS cache and setting it to google's DNS server.
Disabling the VPN on my laptop and restarting VS Code.
Clearing the Extension search results.
Disabling all the extensions currently running.

I'm using a laptop running Windows 10. Any other possible solutions I haven't tried?

In my case, just only sign in with Microsoft Account works for me according to Drew Kimani comment on this question. Please follow this steps:

Open VS Code, click profile logo then click Turn On Cloud Changes
Choose Sign In with Microsoft and follow the next steps.

After done, it will resolve this problem.

It's worth checking if Microsoft's service is online:

https://marketplace.visualstudio.com/

As I write this, it says "Azure DevOps Services Unavailable".

Sorry! Our services aren't available right now.

We're working to restore all services as quickly as possible. Please check back soon.

2024 Settings Specifics for XHR Error in VS Code

The following is relavent - but it is not a root cause. These settings may allow you to install one extension at a time but you have to restart VS Code to install each extension.

1 - Look at Your Settings

2 - Choose Settings From the Flyout

3 - Look at your Application - Proxy settings

The User Settings for your Application - Proxy within VS Code probably should be something different. Notice if your settings are "synced" acrosss devices -this may be relavent to your situation.

I had the same problem, I did the following steps to solve it

All you need to do is enter to the JSON settings file from VSC

Press F1
Type User Settings
Search for Proxy
In proxy section, look for the title Http: Proxy Authorization
Click on 'Edit in settings.json'
Delete all brackets containing proxy data
Save JSON file

After that, just restart VSC You can also find the JSON in %appdata%/Code/User/settings.json

I had the same problem. I had no proxy on the system and no proxy entries in the settings. VS Code could not access the network.

The solution for me was to reinstall VS Code using the "System Installer" instead of the "User Installer", thanks to the hint on this thread: https://github.com/Microsoft/vscode/issues/56657:

Can you uninstall the User Setup and install the System Setup and see whether that fixes it?

yes, i uninstall the user setup and try the system setup, and it works .

For me,it suddenly started working after 4 hours. I don't know if the problem was from my ISP or VSCode Extension server, but it somehow solved itself.

You can also check if http_proxy is set as an environment variable and delete that line if set and no longer on a network that has proxy set-up.

For me the problem was just that my proxy server was on, in my Windows machine. I was earlier working with network tracing, and it seemed to be causing the error.

Problem message:

Solution: resetting proxy settings

So I just turned off everything in proxy settings or you can reset it to default.

In my case, the solution was to remove HTTPS_PROXY (Could be HTTP_PROXY) environment variable set during terminal initialisations.

Environment variables can be confirmed by env command for most operating systems.

I removed the line which sets the environment variable for proxy from the bash profile, then restarted the OS.

Apart from ~/.bashrc for bash or any other sh-compatible shell, the environment variable could be in:

/etc/environment: specifically meant for environment variables
/etc/env.d/*: environment variables, split in multiple files
/etc/profile: all types of initialization scripts
/etc/profile.d/*: initialization scripts
/etc/bashrc, /etc/bash.bashrc: meant for functions and aliases
~/.bash_profile: initialization for login (bash-)shells
~/.bashrc: initialization for all interactive (bash-)shells
~/.profile: used for all shells
~/.cshrc, ~/.zshrc, ~/.tcshrc: similar for non-bash shells

Credit to this post. https://unix.stackexchange.com/a/249922

The environment variable HTTP(S)_PROXY may be used by other applications. Therefore, be aware of the side effects of removing it.

Same problem, updated VS Code on mac while connected to the VPN. After the update I got the XHR Error.

The solution was to stop the VPN, connect to the host and then reconnect the VPN and it seems to work normally. For now.

Same problem, easy solution: just login to Microsoft account and sync settings.

At least try this before all the other more complicated things?

I faced the same problem, however no proxy or VPN. Solved it by entirely erasing my vscode config folders: %appdata%\Code and %userprofile%\.vscode. (As explained in https://stackoverflow.com/a/75473624/2381133.)

This is an issue with the proxy setting.

Press F1
Type User Settings
Search for "Proxy"
Http:Proxy will be empty
Add your proxy here with http://username:password@SERVER:PORT

And just restart visual studio code

I just restarted my entire computer and it worked.

I hate to have this dumb answer. But, I did look into most of the other answers. When something smells like a network issue and you "didn't change anything", it can be many things.

I had this problem in linux,

Manually downloading did not work with an error like: "Request was blocked due to exceeding usage of resource 'Count' in namespace AnnonymousID ..." (I did not save the full message unfortunately). I think Network speed was not an issue because my collage who was connected to same network was able to download extensions.

closing all instances of vscode and re-opening solved it.

If you are using windows 11 with @binjie-liang answer, in your windows search for proxy settings and toggle off the Automatically Detect Settings. This will resolve the issue. Should be same with windows 10 also

Using the task manager I noticed that I had another vscode-instance running that was not closed properly. Shutting every vscode instance down using the Task manager, restarting it I got two vscode-windows, closed one, could install in the remaining one.

I had the same issue .. it's a very specific solution that worked for me but I hope it helps someone who will pass by here in the future:

Apparently .. I disconnected Cloudflare Zero Trust "Warp 1.1.1.1" in the CLI by mistake and some applications (vscode,firefox,skype ..) were using it .. so all I had to do was reconnect .. if your warp tray icon doesn't work like mine then all you have to do is type the command:

warp-cli connect

And all was back to working.

Simply follow below steps:

Press F1
Type User Settings
Search for "Proxy Authorization"
Click on "Edit in settings.json"
Add new key value pair - "http.proxySupport": "on"
Save JSON file

At my end settings.json file

{
    "http.proxyAuthorization": null,
    "http.proxySupport": "on"
}

Running Windows 11, it is Windows Firewall preventing it.

Open Windows Security
Click on Firewall & Network Security
Click on Allow an app through the firewall
Click on Change Settings
Click on Allow Another App
Browse to where VS Code is installed and click on Code.exe
Make sure that Code shows in the list of the allowable apps

And that is it

Hope it works with you as well.

In my case http_proxy system environment variable was set in Windows 10. After deleting that VS code started loading extensions.

I don't use a proxy, and I do use NextDNS so I didn't want to change my DNS settings.

As a workaround, you can open code with --ignore-certificate-errors flag, install any extensions, then restart without the flag.

On windows:

code --ignore-certificate-errors

I faced this problem in 7-2022, and it's gone without even restart vscode. The reason was poor internet connection. If this is ur situation check the quality of your internet connection and just click refresh button, then extensions appear after a moment!

As far as I am aware the XHR error has several possible causes. The easiest fix which should be attempted prior to more complicated methods is restarting VS Code.

I have seen this error a couple of times and have been able to resolve it this way, for me it was not related to proxy settings, whereas for other users it might be. A possible relevant scenario is running a VS Code instance without restart or update over prolongued periods of time, such as days or even weeks.
