Can't Connect To Server

So I am having a little problem since I migrated my old premium account to a mojang account (because I wanted to change my skin).
Everytime I wanna join Wynncraft it says now "java.net.ConnectException: Connection timed out: no further information:", but the weird thing is that I still can join other servers like (NO ADVERTISING) Hive or Mineplex, without any problems of course. And my internet is also fine.
I still havent figured out how to fix this problem and a respond would be nice.
If you can help me don't be afraid of posting a hint.
Otherwise, I wish you a nice day.

 

Have you tried removing wynncraft from your server list and adding it again? This may help. I hope your problem is fixed soon.

 

I tried everything, restarting MC, readd wynncraft, reinstall mc, restart pc, but It didnt help
Today, as I logged in, it worked again, so I am now able to play again.
