Logging me out..

It keeps logging me out and when I try to log back in it says could not connect when my wifi is perfectly fine. Also before it was actually logging me out of it and I would keep having to log back into it which is so annoying. Every time I would open another app or something it would log me out and reset everything:/ please fix this idk whats going on
