I have a dedicated server where i want to run a Modpack on. But everytime i want to join, it says "Authentication servers are down. Pls try again later, sorry!"
When i turn of the Firewall of the server it works, so i think it's something about the ports. I can't find any Ports in the internet.

Can somebody please tell me another solution or the working ports?
