Lost Connection to Server?

I’ve been trying to play since last night, everytime I login, it immediatly tells me that I lost connection to the server

Weird thing is that my buddy, on the same network, logs in just fine…

Tried the following:

DNS change - No dice
PC restart - Same
System restore - Nah
VPN usage - Nope

What else can I do? Feels like I’m banned or something… Quite irritating
