Incompatible FML Modded Server error

I made a modded survival server but i kept getting the error "disconnected" and it said "Imcompatible FML Modded Server Server Network Message List is not compatible" on the right here are the logs btw https://mclo.gs/f81cWZD i was making modded servers for a long time but i never saw this error i checked the logs and it had some errors with supplementaries mod and it said "mod list not compatible" or something. I tried removing the mod and restarting the server (also reset the world) after i did that i got "disconnected" error then i added the mod back and it started saying "disconnected". All the mods are the correct mods btw.

yeah but its the same i checked it a thousand times. also i can't log onto the server it says disconnected. the "Incompatible FML Modded Server error" is at the right like where it shows a server is vanilla or something

i was dumb i missed a mod but it still doesn't work and gives the error "Failed to synchronize registry data from the server, closing connection"

i deleted the mods and the config file then i downloaded the same mods again and it worked ty
