Minecraft pocket edition (android) realm connection issue.

When I attempted to log onto the realms I have purchased I get a prompt along the lines of "cannot connect to realms" and I've tried a few ways of fixing this, I've checked my settings, checked my wifi, Uninstalled and reinstalled Minecraft, logged in and out of xbox live, and well everything that would most likely create a issue. Now I have been able to connect to my realms maybe once or twice after reinstalling it. And shortly after I get the same issue of being unable to connect to my realm.

I can understand that issues like this pop up in excess when trying to update a rather old game, but I have to pay for realms and well don't want to pay and not use it.

I also added a screenshot of the prompt I tend to get. Please respond soon.
