Can't connect to own realm

So, i made a realm plus. The first time i played was okay, but when i left the game and tried to join again, it didn't work. I tried to close down the realm but it says "Unable to connect to realm" i tried to reset the world but it also says Unable to connect to realm. I tried to join, and it worked one time but i cant reset the realm or close it down. I tried it 10 times and it still doesn't work. I checked my connection it was okay, i redownloaded the app and still, it doesn't work. I relogged, and restarted my phone. Please fix this, lots of people have this issue. 1.16.40
