Can't connect to myTeamSpeak anymore

Hello guys,
so basically all of a sudden myTeamSpeak stopped working: i can’t view my badges anymore.

I tried both on TS5 and TS3, basically on TS5 it just kept spinning with connect, so i thought there was some problem and i tried to log out, thing is that now i can’t log back in because i can’t connect to myTeamSpeak, so i am basically locked out of TS5.
So i decided to try with TS3, of course with that i can at least connect and speak on servers, but i always get the red exclamation mark saying that something is going wrong, and myTeamSpeak login doesn’t work, also i’ve lost my badges on TS3 too.

Looking at the log i can see:
14/10/2020 18:18:28 ProtobufRPC Warning Error contacting URL https://clientapi.myteamspeak.com/authentication: SSL_ERROR: Alert on protocol: TLS 1.2 level: fatal error: unsupported_certificate (43)

I’ve read that this error might be related to some antivirus software, so i disabled and removed all but this doesn’t help. I tried to ping and to resolve (and to use the website of) myTeamSpeak and all works correctly.
What i would like to know is if it’s just me or not. To do the best try i could, i moved to my laptop and connected to my mobile hotspot so i both changed machine and connection but still no luck.
Is something going on with myTeamSpeak? I don’t see anyone noticing it so it must be just me…

Any idea of what i could try?
Thanks in advance
