"general error Top-level error" when trying to connect to the server

[DeMiro5001]

Hardware : old laptop i3/3Go/500Go / ADSL
Software : YunoHost 4.2.8.3 (stable)
No special config, port forwarding ok, SSL certificate ok, no ipv6, only ipv4

I'm getting the metronome service to stop working as soon as I try to connect to it, I tried Converse, Movim, conversations.

It's been weeks that I was trying to search to understand what's wrong without luck.
Thanks a lot.

What version of Metronome is it? If it's not 3.14.4 try updating the package.
Also that error is related to server to server connections not client to server, are you using custom connection settings on the client? Like specifying ports?
