Hello,

first of all, sorry for any writing mistakes, as English is not my first language :)

I tried to make a new Private Server, after I didn't played for some time and wanted to test out the new Stuff added with the latest updates.
I rented a root Server from a Host that I used the last three times, which always worked just fine.
I got through the usual set up. Downloaded the Server via CMD, Set Up the Ports and everything.
But when I click on my Server in the Server Browser List, the game just does something for a few seconds, and then I get the Error as described in the Title. After that, for unkown reason I cant even try to reconnect to the Server, until I restart the Game.
I tried to verify the Server Files, my Game files. Tried reinstalling both, tried the experimental files. Nothing works, so I'm pretty sure it has something to do with the Server connection or something like that, but I'm pretty confused as the Server is standing in the Server List. Even in the Steam Server List if I add it with a Ping between 30-60.
