after updating my client to version 3.1 today it won't start anymore. The error message reads:

TeamSpeak fails to start because it cannot find any port.

Terminal output:

I suspect this happens because my kernel is missing IPv6 support entirely. Enabling it in my environment involves some work so I did not verify this theory yet. The addition of IPv6 support is also mentioned in the changelog. It isn't listed as a mandatory requirement though.
