Can't connect to Realms Server

Hello i tried today to login into my Realms server but for some reason i coulnd't login. I am still at the 30 days trial but my card has enough money for the renewal. I restarded the game and my PC several times and even deleted and downloaded again the game. Some time it showed the error 500 but after 10 minutes it went away. The game is in the latest version 1.21
