try to get as many people as possible to vote on this post so Mojang sees it faster
it's on Mojangs side their server has an error we have to wait for Mojang to fix it
This happens when I try to go to the minecraft realms tab on java and appears to have something to do with the realm list server.
This is on vanilla 1.21.5 and tried on multiple accounts and I think no one can access realms right now
fixed
