Can't connect to UN

[knightfire35]

I was playing Unholy Nation and I randomly got disconnected from the game. Every time I try to log on it says that I can't connect to the server.

I have tried:
-reinstalling Graal
-restarting my internet and computer

I can connect to other servers fine, why all of a sudden can't I connect to UN?

It's not my computer, I tried on my laptop as well and it wouldn't let me.

Any help would be appreciated.
