The minecraft team is aware of the issue

Some folks (including me!) have reported having trouble connecting to W10/PE realms. We are aware and working on a fix! Hang tight.

From Shoghi Cervantes (one of the MCPE devs)

We just fixed some issues on the Minecraft Pocket/Win10 authentication servers today, making you unable to enter Realms. All fixed now!
