Describe your issue

The issue is, that I want to connect to a server with the Create 5 Modpack from Modrinth, I have the Java Files from Modrinth, but start the mods over the official launcher due to privacy concerns from my side with my Microsoft Account.
It is the same version, and even after getting the Java File from the server side the same problem occurs.

Crash report/logs

Failed to synchornize registry data from server, closing connection

Okay, thanks!

Do you know a way, of getting in contact with a creator of a modpack on Modrinth?

Copied from the discord:

Forge is not the smartest. The criteria it judges 'version differences' on is not just the version number, but also what registry objects (like items and blocks) exist.

This means that when you add custom things with KubeJS, Forge can sometimes show a version mismatch error with the exact same versions shown on both sides.

The simple solution for this is to make sure that the startup_scripts folder is the same on client and server.

If this isn't your pack and you're sure you installed everything correctly report to the modpack devs

If they don't have a GitHub or discord or any other means of communication linked then i don't thinkg there's a way on modrinth, though i don't know really cause I haven't used modrinth . Maybe Check If they also have a curseforge.

this error shows up if the startup scripts in the kubejs>startup_scripts folder are not the same on the client as it is on the server. Both server/client must have the same scripts otherwise there are registry issues which result in this error being the case
[edit: i also just realized mund already told you all this]
