Unable to connect

Okay so I've downloaded the v83 setup and client files from the website, but I cant connect to the server from both of the clients.
One of them gives me a server maintenance issue, the other one gives me this:-


I tried to download Eric's client, I've tried downloading the files with antivirus/firewall off, but it just wont work.

Please help, thanks. ^ ^

you gotta wait bro that's what i get either sometimes it is because they restart the server and you will need to wait for awhile to play sometimes you need to wait for quite long lawl

That usually pops up when the server is down. If you try later it should work.(cause the server will be on)
