I'm having a really weird issue where my server can't authenticate players that try to join. A vanilla server works just fine, but even forge with no mods causes players to no longer be able to join. Setting online-mode to false in server.properties allows players to join again, but that obviously isn't a permanent solution. The only config option I have changed is fullBoundingBoxLadders.
I am running a fresh install of lubuntu 22.04.1 with openjdk-17, Forge 1.18.2, tried both 40.1.86 and 40.1.74
