Hello. 

My friend recently created a realm for 5 of us to play on. The 5 of us can log in fine, but the host is unable to log in and is forever stuck on the "Loading Realm" screen. They have tried uninstalling, restarting their PC, messing with the WiFi router, uninstalling VPNs, turning off antivirus software, logging in on their phone, deleting and backing up the world, and nothing is working. They were able to play just a few days ago, but its suddenly not working. Please help.
