Help Im Baned but im Not?..

Hello,

Im new to this Server and enjoy it al lot.

but I tried to log in and it said, my Account hat been blocked but can be unblocked or so (Im German).

On The Website everything seems fine and im not rlly blocked..

I tried everything like deleting my Chace and WTF folters and logged in on the Webside a few Times (also restarted my Internet A few Times)..

I dont know what causes the problem..
My Router resets itself every day and maybe get a new Ip Adress.. I dont know.

But i logged myself in on the website and everything worked the last few days.. but today it will not work..

please help
