Hopefully, I'm posting this right. This is copy-pasted from a Reddit page I asked(I didn't get any answers):
For the past week, I've been trying to fix this with no result so I'm asking here. I'm in an SMP with a few friends, it's on fabric and uses the origins mod.
Problem is, I can't log on, it loads me in just fine (takes a while longer than usual though) but once I've loaded in for a few seconds it kicks me with no error message other than "Connection lost". At one point after reinstalling multiple things, the server would just sit pinging forever until it, too, would say something about lack of connection. It's back to doing the first thing now, though.
The other SMP members have told me that I do log in, but I quickly log out when this happens. I can do things like run around and explore but if I place any blocks they do not show up for the other members, and I can only do these for a few seconds before I'm kicked. I usually get kicked around a second after my subtitles load in if it matters.
I've reinstalled fabric and the mod, reinstalled the entirety of Minecraft, and edited my firewall, and logged out and back in, and like a thousand other things, but still no fix. I don't know what caused it. Can anyone help?
