However, sometimes you may encounter an error message that says "XHR failed" when you try to search for or download extensions in VS Code. This error prevents you from accessing the extensions you need and can be very frustrating. In this article, we will explain what this error means, why it happens, and how to fix it.
What is XHR Failed Error and Why Does It Happen?
XHR stands for XML HTTP Request and is a method of sending and receiving data over the web
XHR is a technique that allows web browsers to communicate with servers without reloading the page. It is widely used by web applications to provide dynamic and interactive features, such as autocomplete, live search, chat, etc. XHR is also used by VS Code to fetch extensions from the marketplace.
XHR Failed Error occurs when VS Code cannot fetch extensions from the marketplace due to network or proxy issues
When you try to search for or download extensions in VS Code, it sends an XHR request to the marketplace server and expects a response. However, sometimes this request may fail due to various reasons, such as:
Your internet connection is slow or unstable
Your firewall or antivirus software is blocking the request
Your proxy settings are incorrect or incompatible with VS Code
The marketplace server is down or overloaded
The extension you are looking for is unavailable or corrupted
When any of these situations occur, VS Code will show an error message that says "XHR failed" or "Error while fetching extensions. XHR failed". This means that it could not receive the data it needed from the server and could not display or install the extensions.
How to Troubleshoot XHR Failed Error in VS Code
Check your internet connection and firewall settings
The first thing you should do when you encounter the XHR failed error is to check your internet connection. Make sure that you have a stable and fast connection that can support data transfer. You can test your connection speed by using online tools like .
You should also check your firewall settings and make sure that they are not blocking VS Code or its requests. You can temporarily disable your firewall or antivirus software and see if that solves the problem. If it does, you can add an exception for VS Code or adjust your firewall rules accordingly.
Check your proxy settings in VS Code and your system
If you are using a proxy server to access the internet, you need to make sure that your proxy settings are correct and compatible with VS Code. A proxy server is an intermediary that acts as a gateway between your device and the internet. It can help you bypass censorship, enhance your privacy, or improve your performance. However, it can also cause issues with some applications that require direct access to the internet, such as VS Code.
To check your proxy settings in VS Code, you can go to File > Preferences > Settings and search for "proxy". You will see two options: "http.proxy" and "http.proxyStrictSSL". The first one is the URL of your proxy server, which you need to enter in the format " The second one is a boolean value that determines whether VS Code should verify the SSL certificates of the proxy server. If you are using a self-signed or untrusted proxy, you may need to set this to false.
You should also check your proxy settings in your system and make sure they match with VS Code. Depending on your operating system, you can find these settings in different places. For example, in Windows 10, you can go to Settings > Network & Internet > Proxy and enable or disable the proxy server. In Mac OS, you can go to System Preferences > Network > Advanced > Proxies and configure the proxy server.

Clear the extension cache and restart VS Code
Sometimes, the XHR failed error may be caused by a corrupted or outdated extension cache. The extension cache is a folder that stores temporary files related to the extensions you have installed or searched for in VS Code. It helps VS Code load extensions faster and reduce network traffic. However, it can also become corrupted or outdated and cause problems with fetching extensions from the marketplace.
To clear the extension cache and restart VS Code, you can follow these steps:
Close VS Code if it is running
Open the File Explorer (Windows) or Finder (Mac OS) and navigate to the following folder: %USERPROFILE%\.vscode\extensions (Windows) or /.vscode/extensions (Mac OS)
Delete all the files and folders inside this folder
Open VS Code again and try to search for or download extensions
This will clear the extension cache and force VS Code to fetch extensions from the marketplace again.
Download and install extensions manually from the VS Code website
If none of the above methods work, you can try to download and install extensions manually from the VS Code website. This way, you can bypass the XHR request and directly get the extension files from the source. To do this, you can follow these steps:
Go to and search for the extension you want to install
Click on the extension name and then click on the "Download Extension" link at the bottom of the page
Save the extension file (.vsix) to your computer
Open VS Code and go to File > Preferences > Extensions
Click on the "..." menu at the top right corner of the extensions panel and select "Install from VSIX..."
Browse to the extension file (.vsix) that you downloaded and click "Install"
Restart VS Code and enjoy your extension
How to Prevent XHR Failed Error in VS Code

Use a reliable VPN service if you are behind a proxy or firewall
If you are behind a proxy or firewall that restricts your access to certain websites or services, you may face problems with fetching extensions from the marketplace. In this case, you can use a reliable VPN service that can help you bypass these restrictions and access any website or service you want. A VPN service is a virtual private network that encrypts your data and routes it through a secure server in another location. This way, you can hide your IP address and location and appear as if you are accessing the internet from another country.

<ul The speed and reliability of the VPN service
The security and privacy features of the VPN service
The compatibility and support of the VPN service with VS Code and other applications
The cost and customer service of the VPN service
Some of the popular and reputable VPN services that you can try are . However, you should always do your own research and read reviews before choosing a VPN service.
Sync your Microsoft account in VS Code to access extensions across devices
If you use VS Code on multiple devices, such as your laptop, desktop, or tablet, you may want to sync your extensions across them. This way, you can have a consistent and seamless coding experience on any device you use. To sync your extensions across devices, you need to sign in to your Microsoft account in VS Code and enable the settings sync feature. To do this, you can follow these steps:
