i cannot connet my own sever, i get " fatally mising registy entries error, pls help me. Here is my log https://mclo.gs/s2ouU7b

from the looks i think you installed newer mods on the server and then downgraded and the world dosent work, im not sure how to fix it

Make sure that the EXACT same mods installed on both your PC and the server. It is not enough to simply have the same mods installed, they must also be installed in the exact same version. Likewise, the version of the mod loader (Fabric/Forge) must be identical.

If you use a Modpack make sure you're running the same version as the server.
