Unable to connect to my realm

Hi,

I'm trying to connect to my realm but it just shows Connecting to the realm....

After a while it goes to An error ocurred, please try again later.

This issue is the same for a friend of mine so it's not related to my internet it seems.

 I tried closing the realm, switching map. The map is still downloadable and openable in singleplayer so the map is not corrupted.

Cheers
Sebastian
