    I tried to connect on a server i created (1.12.2 version) with a few mods, but when i try to join it i get the message "Fatally missing entries". I know it means theres a problem with the mod so i checked that the client and the server have the same mods installed, and i also checked that the versions of the mods were the same, and everything was correct, but it still doesn't work.

    I tried to delete the mods one by one just to see, and it worked when i deleted the mod SCP Lockdown. But i don't know what to do to solve the problem without deleting the mod.

    Can somebody help me?
