Disconnected from server issue

Well hello there, today i played alot till 12 AM , i logged out and tried to login again , when i tried to join UK same as NA this problem happens to me , and i think it happens to everyone because look at the servers its not full , and when i enter UK or NA it stays for a long time and gives me this : 'Disconnected from server'
