So me and a friend of mine are having some issues with the server. it's just a LAN server but when she tries to join it always says "failed to synchronize registry data from server" we tried to update our modpacks to the correct version, repairing our modpacks, I also even tried to do research for the error, but I'm not exactly sure it's a mismatch with the mods... at this point I'm really confused and lost on what to do
