I was playing on my realm with friend earlier and had no issue. Logged off for a while and tried to connect recently. I get text on my screen that said "unable to connect to world". This happened the day before (Friday) as well. I downloaded a previous save file and it seemed to have worked for today but it's doing the exact thing again and so far what I tried this morning isn't working. 

I'm hoping for a fix soon because we've worked extremely hard the past two weeks for all our stuff and I'd hate for everyone to lose the progress we've made. 

I tried everything to fix this, even uninstalling then reinstalling the game. No luck.
