I own a realm subscription that me and several of my friends regularly play on. I have had an issue for a while, where every time I try to join it, I get booted after a few seconds with the error "connection lost" and am returned to the realms menu. Previously, I was able to brute force this issue by retrying connection over and over, then it would finally let me in. Recently that no longer works, and I am only ever able to be in the world for no more than a minute. Turning on a VPN does not fix the issue, unless I connect to a server that makes the connection too laggy to enjoy. I usually play with some optimization mods installed, so I attempted running a completely vanilla version of the game, without a VPN, my firewall turned off, with a flushed DNS, and I still can only play for 2 seconds before I am booted again. All of my friends, even the ones with less than ideal internet, can connect and play without issue. I am connected to my internet through ethernet, and my connection works fine everywhere else, I am even able to join other minecraft servers. The only thing I am not able to do, is join my own realm. I've seen multiple other people with this issue, and I was unable to find a solution that works. *FIXED*
