Launcher Type Curse App

Modpack Sky factory

Modpack version 3.0.15

Details of the issue I'm hosting a private server for some friends so I made a forge server and copied the files from the modpack into my server folder. I have done this with other modpacks(not FTB) When I try to join it gives me this error(https://imgur.com/a/F0Mwdw6)(Internal Exception: java.lang.IllegalArgumentException: The name extrautils2:synergy has been registered twice, for Block(null) and Block(extrautils2:syngergy). Singleplayer works fine, so it has to do with server configs right?

Use the provided pre-made server zip-file instead, and you should be good.
