I recently created my own server with mods ... and added this fantastic mod so that players can steal each other ... but when using the pick it does not work, the minigame tab does not open to open the lock.
The version of the mod is 2.5 for 1.12.2.
If it works when I play the single player but when I enter the server it does not work for me. Can you help me?

Can you check if this issue occurs in the latest Locks version for 1.16.5 as well?
