Urgente bisogno di aiuto per il mio server teamspeak

[Gioele]

Ok ho chiesto al supporto di extravm e questo è come mi ha risposto l'operatore (è in inglese):

Hi,

We don't block any TCP traffic. If it's not working for you then your software firewall (iptables?) is blocking it or it's an issue with the application.

The errors in the log you posted say "Failure in name resolution", this is related to DNS servers not being set in /etc/resolv.conf.
