[Bug]: Terminal not accessible

[dickermoshe]

Error Message and Logs

I've installed coolify on a spare laptop.
I used Cloudflare tunnels to access it remotely.
I set the correct environmental vars so that the the realtime and terminal api should work on the frontend.

REALTIME websockets work, But TERMINAL websockets do NOT!

Steps to Reproduce

1. Install Coolify on a Server
2. Navigate to Terminal Page
   ERROR: Terminal websocket connection lost.

Ok, let's use curl on localhost to see what's going on:

root@oldlaptop:/home/mick# curl localhost:6002/ready
OK

Seems like the server for the realtime API is running, that's good

Let's get those logs:

Hmmm, looks like everything is ok.
Let's try copying the request from chrome and seeing if it works from the CLI

We can use a tool like websocat to test if this works locally:

root@oldlaptop:/home/mick# websocat 'ws://localhost:6002'   -H 'Upgrade: websocket'   -H 'Origin: https://coolify.dickersystems.com'   -H 'Cache-Control: no-cache'   -H 'Accept-Language: en-US,en;q=0.9'   -H 'Pragma: no-cache'   -H 'Connection: Upgrade'   -H 'Sec-WebSocket-Key: RB72t/uvO8ejOMLhMQljUA=='   -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36'   -H 'Sec-WebSocket-Version: 13'   -H 'Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits'
websocat: WebSocketError: WebSocketError: Received unexpected status code (400 Bad Request)
websocat: error running

Hmmm, it doesn't. No logs in docker logs either. Seems like we need better logging!!

We can confirm that copything from curl SHOULD work by copying the request from the realtime websocket that is working.

root@oldlaptop:/home/mick# websocat 'ws://localhost:6001/app/REDACTED?protocol=7&client=js&version=8.3.0&flash=false'   -H 'Upgrade: websocket'   -H 'Origin: https://coolify.dickersystems.com'   -H 'Cache-Control: no-cache'   -H 'Accept-Language: en-US,en;q=0.9'   -H 'Pragma: no-cache'   -H 'Connection: Upgrade'   -H 'Sec-WebSocket-Key: +has5XTnkQrT1iRzO6Lx3g=='   -H 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36'   -H 'Sec-WebSocket-Version: 13'   -H 'Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits'
