Thread: Game Issue after the last Update

Hello, I seem to have an issue with the game at the moment. Every time I go to battle one of the bosses, for the first fight the game freezes for like 10 sec, same thing happens when I'm going to Battle other players, again the game freezes for like 10 sec. I'm playing on Nutaku and I'm using Firefox. I was getting an Error at some point but now it just freezes for 10 sec.
Never had any issues with the game before.

Edit: The error is 503 - Server is not responding
