Description of the Bug
I cannot craft the backpack on my local server. When I go into a local Singleplayer World, I have no problems with the same Fabric-Installation and mod-files. I can see the backpack in JEI even on the server.
The Server is started via CrowdControl.

Steps to Reproduce
Starting the Server via CrowdControl, entering the world and trying to craft the backpack. I can see the backpacks in JEI, but I also cannot click on them to see the recipe.

This sounds like you don't have the mod installed on the server. Can you share the logs from the server?

I found the solution, it was a mistake on my side. Thanks for the hint.
I did not know that there is a different mod-folder for the local server. I had to put the mods in there, too.
I was very confused, because the backpack recipes were displayed in the game and all the other mods (maps, JEI, ...) also worked, which I only put in the mod folder from the original Minecraft-Folder.

Sorry for bothering you. Maybe someday someone will face the same issue, so I will leave the folder-path here:

C:\Users\%USERNAME%\AppData\Roaming\CrowdControl-Apps\Minecraft\Fabric\mods

Thanks!
