Fatally Missing Registry Entries 1.12.2 Forge

Hi I am trying to connect to my own server with forge 1.12.2 installed but I am using two different launchers called MultiMC and GDLauncher and both of them had the same error pop up "Fatally Missing Registry Entries"

Can someone help me fix this please?

Thanks!

Make sure you have the same collection of mods installed on client and server.

Deleting the config folder on client and server can also help.

i have all of the same mods installed but i need optifine for one of the mods(vics modern warfare) otherwise it kicks you out of minecraft completely when going into a tab(in creative menu) but this has never happened before

i just deleted both config files and started up the server and game... it didn't work.. still getting the same error
