ERROR_failed_connection_initialisation while connection (Android)

I can not connect a server. I always get this error "ERROR_failed_connection_initialisation while connection".

My Smartphone: Sony Xperia Z3 Compact with Android 5.1.1

Here is the Logfile from the Teamspeak App (I tried to connect to the official server):
