Hello,

I'm having a trouble connecting to WSS websocket. I'm using self-signed certificate.

Firefox shows in the console: Firefox can’t establish a connection to the server at wss://127.0.0.1/...

I have tried with private browsing and with troubleshoot mode.

Works out of the box in Chrome and Brave.

Firefox: 105.0.3. OS: Ubuntu 22.04.1 LTS
