Expected Behavior

If I set an http network proxy on my Insomnia preferences I want all my requests to go through that proxy, including ws/wss connections.

Actual Behavior

Even though I have a proxy configured, WebSocket requests are not going though that proxy. All other normal http/https requests do go through the proxy.

Reproduction Steps

1. Create a new WebSocket request
2. Test it without any proxy settings, verify it works
3. Configure a proxy under Insomnia preferences
4. Try to make a connection with that same WebSocket request, observe that the request still works but it does not go through the proxy

Is there an existing issue for this?

• I have searched the issue tracker for this problem.

Additional Information

The proxy in question is mitmproxy which I use regularly to capture and analyse traffic. I am able to observe all other http/https requests I make from Insomnia on the mitmproxy interface, but not the ws/wss connections.
I do see ws/wss connections made by my application on the mitmproxy interface.
If I turn the mitmproxy off but leave the proxy settings configured on Insomnia, the WebSocket request still works (meaning is not going through the proxy) but all other http/https requests wouldn't work, as expected.
