Can't use with cloudflared tunnel: stream error: stream ID 3; PROTOCOL_ERROR

[bbigras]

The websocket connection works when I'm testing on my machine with localhost but for some reason, when I'm using it deployed with cloudflared the websocket opens but closes immediately with an 1006 error code.

If I test with the "simple websocket client" Chrome extension, I get the same problem. But if I try a simple nodejs websocket server, it works, so I'm guessing maybe the problem is with tide-websockets.

Also, it seems that my backend is sending data to the websocket, but I don't get it on the browser side.

Don't hesitate if you want me to test anything or provide a cloudflared config file example.

tide-websockets: 0.4.0
tungstenite: 0.13
async-tungstenite: 0.13.1
