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, the solution was to remove HTTPS_PROXY (Could be HTTP_PROXY) environment variable set at terminal initialization.
I removed the line which sets the environment variable for proxy, restarted the OS and the error disappeared.
Apart from ~/.bashrc for bash or any other sh-compatible shell, 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

For me , 'XHR failed' error appears when the proxy settings between your PC system and vs code are conflict.
1.Check PC system proxy settings.
2.Open cmd or terminal, type
echo %http_proxy%, if any output, make sure it fits your pc proxy setting. Because if the proxy on vs code not being set, will be inherited from the http_proxy and https_proxy environment variables.
3.If none, open vs code settings.json , add
"http.proxy":"http://proxyname:port" that fits your pc proxy setting ,without a trailing slash.
Try download extensions again.Hope this helps. ^^
