Can't log in

Hi, just registered for the server and when I try logging in the login button becomes greyed out but just stays there. I've tried restarting my router and my computer. Any help would be appreciated!

 

Do you get a message that pop's up after the login button stays pressed ("gray")? Does it just stay gray?
Can you log in now?

 

can't log in still. And it just stays gray

 

Nevermind its working now, laptop kept disconnecting from the wifi randomly
