Receiver visible on iPhone's list but cannot connect

[raftutak]

The problem

Hi. I set up a receiver using docker compose. The receiver is visible then on my iPhone and MacBook, however I'm unable to connect. Before it started to be visible on the list I whitelisted required ports in ufw but as I mentioned I cannot connect.

Am I still missing something?

Below are the logs:

My best suggestion would be to disable the firewall, and work backwards from there. ControlPort and DataPort which the are advertised need to be accessible - but those are usually assigned in the non-root port range. So leaving those UDP ports open is a good idea.
