How to Debug WebSocket Problems with Apache's mod_proxy_wstunnel?

Debugging WebSocket Issues Behind mod_proxy_wstunnel

When setting up a WebSocket server behind Apache with mod_proxy_wstunnel, users may encounter difficulties. To debug these issues effectively, it's essential to examine the following:

Request Routing:

• Ensure that the ProxyPass directive for the WebSocket path (/ws/) is ordered before the general / ProxyPass.

Trailing Slash:

• Add a trailing slash to the WebSocket path configuration, as mod_proxy_wstunnel expects a valid GET request with a URL-encoded path.

Origin Check:

• If the WebSocket server includes an origin check, such as in the ServeWs() function of the Chat example, remove it to prevent conflicts with mod_proxy_wstunnel.

Additional Debugging Tips:

• Consult the server logs to identify any specific error messages that can provide insights into the problem.
• Verify that the WebSocket server is running on the correct port and is accessible via SSH tunnels.
