Hello,
last week I rented a "cheap" linux vserver (via

).
Afterwards I've installed Teamspeak³ on the server and configured everything correctly.
I've also rented the domain

and created the subdomain ts3.fa-it-solutions.de.
I've also spend a few hours with friends on the server over the last few days and everything worked until today.
Today I've recognized connection issues via Teamspeak³ from my PC to the Server. Sometimes I get disconnected from the server and then I've problems to reconnect for several minutes.
While my Teamspeak Client can't connect, I can connect to the server via server query and my ping or ssh terminal to the server won't get connected too.

My TS3Index Server Viewer is probably working too:
I guess that this will probably be a problem on the site of my hosting provider, but I'm not sure.
Does anyone have other suggestions or tipps? could it be a missconfiguration on my vserver?
Thank you beforehand
