Hi! I keep on getting this same issue when i try to join a server with this mod installed.

Please tell me what datapacks and other addons you have, the issue lies in the server trying to sync its origin data with the client, I doubt it's this mod doing it.

Additionally, what MC version are you on?

Something I'd also like to check is have you modified any of the TooManyOrigins origins and if so, a broken power there is not a bug regarding this mod.

Okay new thing I'd like to check. Do you have this mod installed on your client?

There probably would've been a message booting you out if that were the case...

I'm boiling this down to a registry desync, which is not really an issue with this mod and moreso an issue of the user not having certain mods on their client that the server has.
