VS code "error while fetching extensions xhr failed" solution.

The "error while fetching extensions xhr failed" message can also occur in Visual Studio Code when there is a problem with the editor's ability to retrieve data via an XML HTTP request (XHR). Here are some potential solutions you can try:

1. Clear Visual Studio Code cache: You can clear the Visual Studio Code cache by opening the Command Palette (Ctrl + Shift + P on Windows or Command + Shift + P on Mac) and typing in "Developer: Reload Window with Extensions Disabled". This will disable all extensions and reload Visual Studio Code. Then, try accessing the extensions again.

2. Check your internet connection: Ensure that you have a stable internet connection by restarting your router or modem and connecting to a different network if possible.

3. Update Visual Studio Code: An outdated version of Visual Studio Code can cause various issues, including XHR errors. Check for any updates to your editor and install them if available.

4. Disable firewall or antivirus software: Sometimes, firewalls or antivirus software can block XHR requests. Try disabling your firewall or antivirus temporarily and see if it resolves the issue.

5. Check your proxy settings: If you are behind a proxy server, you may need to configure Visual Studio Code to use the proxy. Go to File > Preferences > Settings and search for "proxy". Then, configure the "http.proxy" and "https.proxy" settings with your proxy information.

If none of the above solutions work, you can try reinstalling Visual Studio Code. If the problem persists, it may be a server-side issue that you cannot fix, and you may need to contact the Visual Studio Code support team for further assistance.
