Error message, why ?

In the game, i have the error message ("NOTICE: you cannot connect to the server please try later."). what is the solution for this problem ?

Thanks :)

That means you cannot connect right now, and you should try later.
Whats not clear?

Try closing all unnecessary processes or restart your pc.
