Same thing happened to me
I had to remove my windows productID to connect to the TS
Don’t actually know what this does or what could go wrong when it’s removed but I live life on the edge so who cares

I did the same back in the day when I used to mass ban evade to go on the teamspeak, it really goes to show how dedicated I was to zarp that I was willing to potentially brick my pc just for a few giggles
