Blue's bitminers 1 (rip) not working.

Hello! I have code blue's bitminers 1 addon and when I added the entities to my F4 menu, they don't spawn when I click on them on the F4 menu. I have used them in the past on a local server and it worked but its now 5 months later and I'm using a hosting site and they just don't spawn. I checked the entity names and they are correct. If anyone know whats wrong, please help. I have been trying to fix it for a while and it's very frustrating. Thank you and rest in peace <CODE BLUE>
