Fixed the issue, one config didnt match, downloaded randompatches to solve badly compressed packet afterwards.

Not sure if this helps, but I copied all of the mods from my folder into a zipped folder which was then sent to my friend for them to unzip and drop all of the mods into their mod folder, the same goes for the configs.

Trying to play on a modded LAN server with my friend, when I try to join their LAN world I get the "Failed to synchronize registry data with server, closing connection" message, and they get the same message when trying to join my LAN world. We have the same forge version 35.1.12, all the same mods with the same versions of those mods as well as the same configs.

I just found the issue actually! I must have been blind, there was a misnamed mod on her side so its solved now, thanks!

Trying to connect to my friends modded LAN server, we are both in the same house using the same wifi. We have the same forge version on both sides as well as mods and their versions. Her server appears in the local servers and when I try to join it just says "disconnected" on the first attempt and then any time after that says "failed to synchronize registry data from server, closing connection." I have never encountered this issue before and the internet provides little help so far. My forced crash log: https://pastebin.com/T2ajXkmd My friends forced crash log: https://pastebin.com/Ktgsk60a
