Problem found. Please read the notice in the mod description:

*** IMPORTANT NOTICE FOR TS3 BETA 15 AND HIGHER ***

With the latest release (Beta 15) of the teamspeak 3 server, ts3 has introduced a query flood protection which bans every ip, which queries the teamspeak server too often in a short period of time.
To exclude ips from this procedure, edit the query_ip_whitelist.txt in your ts3 server directory.
For those who don't have access to this file, consult your service provider.
The next major version of this plugin will include some techniques to deal with this limitation. Stay tuned.

Also notice, that the newest ts3 server version (beta 15) requires client version of beta 11 or higher.

Please read the version notes and the documentation of teamspeak3 itself to get further information: http://www.teamspeak.com/?page=home
