I have gone to setup a new 2 player realm today, paid the subscription fee, and when trying to get the world setup it displays the attached error. I've tried to close the screen, restarted the game and tried on another device but the realm will still not create. 

I've setup 2 realms before and they are working fine so I'm unsure why this one will not create and what need to be done to get it going.

I would appreciate your help getting the realm active so I can invite e of my friends.
