I have a concerto server running with a player connected without problems.
Now I would like to connect a second player but when I type url for the server (that really runs) I get "Failed to set URL: Could not connect to Concerto Server".
I can ping or ssh to this recently created player and it is on same network range as server (no firewall in the path).
If I can't set up this URL I can't get the token so I can't register on server.
What could be wrong?
