VS Code Proxy Troubleshooting

CodeTogether supports proxy servers in 2 different ways: VS Code built-in proxy support, or via a custom codetogether.proxy setting.

VS Code Built-In Proxy Config

This is enabled in VS Code by configuring the http.proxy setting.

Example: Set http.proxy to

Note that it might not be compatible with all kinds of proxy servers.

If CodeTogether is still not connecting correctly through your proxy, you can try disabling the proxy support for extensions by setting http.proxySupport to off.

CodeTogether Proxy Setting

If CodeTogether is unable to connect using VS Code’s built-in proxy support, you can use the codetogether.proxy setting to specify the proxy server that should be used by CodeTogether.

The value is an object with the following structure:

host: string;
port: number;
type: string ("http" | "https" | "socks5");
// Auth is optional
auth?: {
user: string;
password: string;

For example:

"codetogether.proxy": {
"host": "",
"port": 8080,
"type": "https",
"auth": {
"user": "myuser",
"password": "mypassword"

For these settings to be taken into account:

  • You must disable proxy support for extensions by either removing the proxy.http setting, or by setting http.proxySupport to off.

  • You may need to ensure that related system level environment variables are not set for the environment in which VS Code is running. For example, http_proxy and https_proxy on macOS.

To set codetogether.proxy, use the VS Code settings editor:

Debugging Connectivity Issues

In CodeTogether settings, turn on the CodeTogether: Debug setting and restart VS Code. The extension will now log to the CodeTogether Debug console in the Output view.

For On-Premises Users

  • Check the log for the _currentUrl value-this should be an HTTPS URL, not HTTP.

  • The fully qualified domain name in the above URL must match the configured value for CT_SERVER_URL.
