I just tried; and it works on my end.

Can you try adding wss://groups.0xchat.com to your general relays? I was wondering whether you can successfully connect to the relay.  

 I'll try that.
Because on groups.fiatjaf.com it did work indeed!
Thanks. 

 Thanks, I think it's most likely because you are not able to connect to groups.0xchat.com. I'll see if I can provide a more user-friendly error message for this
