So I wanted to play CS:GO again with my friends and created a Dedicated Server. I followed the steps on the Valve Developer Community Website and the Server just works fine (I didn't Port-Forward yet I just wanted to test if the Server works in my LAN) the Problem is if I want to connect I see the loading screen for like 3 seconds and then get back onto the Homescreen and I get the Pop-Up that the Support for CS:GO ends January 1st 2024. But I thought community Servers should still work right? The weird thing is when I am trying to connect to the Server, the Server executes its server.cfg but then because I didn't actually connect it goes back to hibernating.

Can somone help me please?
