My sister and me were playing for some days in a world via LAN. We are using about 30 mods, and since today when she wants to connect she gets the message "Failed to synchronize registry data, closing connection".

I have no Idea why this happens, I updated all mods and forge and made sure we are using the same versions.

For some reason, when i create a new world and open it to LAN she can join, but I dont really feel like doing everything again. Has anyone an Idea why this could occur and how to fix it?

As I said we were playing together, then she disconnected and tried to connect again about an hour later, but the Error occured. We both didtn change anything at our installation.

Oh here are the logs in case needed:

latest.log

clientconeccting.log

These blocks are present on the hosting client, but not the connecting client. Ensure that mod versions match exactly between the two.

If that does not fix it, also ensure the configuration files match - however in that case you need to report this to the mod author, as configuration files should be synced from the server to the client.

Seems weird to me, we deleted those mods some time ago since they were bugged for some reason, and played after that sucessfully, but i wíll try adding them thank you

ok it is kinda working now, i think i can fix the rest by myself. Thanks for the fast help!
