Hello,
after installing the newest beta Im no longer connected to the chat service, but joining servers is working.
Im using a Mac and I already checked my firewall, but nothing regarding Teamspeak is blocked there.
Message me and Ill send you my logs.
I just logged out and back in, still no connection to the chat.
on win10 it works well to me
Hi, i have this problem too. Im in contact with some guys from Teamspeak who are trying to figure out what is causing this problem.

Looks like I also still got the audio thing @TS_Dennis
The interesting things would be in tschat.log
This looks almost 1:1 to my logs 
@nx1 can you please install b32 again and see if chat works for you?
Installer from https://beta.teamspeak.com/ are still b32.
Just did this, everything is working fine.
