Why does Hamachi Minecraft Modpack Server not work? (Fatally missing registry entries)?

I tried to create a server for Forge and Hamachi for the mod "Hexxit Remastered" (Downloaded by Twitch) according to this tutorial:

Everything worked very well. The server is theoretically even online but Minecraft then displays this error message: "Fatally Missing registry entries" The server console then shows that I would have left the game even though I was not on it at all. (See the screenshot). Also, the server says "106 mods present" even though the modpack contains 112 mods (it's in the menu).

I'm sure I copied the whole modpack folder.

Is anyone able to help me?

City to try to play a Hexxit modpack you could join our mod project. It's called "Warfare" and it's about 3 tribes fighting each other. There are 8 mods and it is in version 1.10.2
