    Hey, so I'm having issues with connecting to my server. The server runs on Mohist 1.12.2 with several mods along with some optimization mods to reduce the lag the other mods put on the server. I tried to connect but all it gives me is Fatally Missing Registry Entries. Here are the logs for it https://mclo.gs/dqeKQs0 and if anyone has a quick solution, please do help me

    The error message "fatally missing registry entries" typically appears when the installed mods on the player's computer do not match the installed mods on the server.


    For modded servers, players must have the exact same mod collection installed on their computer as the server.

    It is important that the version of the installed mods is identical as well as the version of Forge itself!


    If you have so called client-only or server-only mods installed, it may help to temporarily remove them.
