I want to play the modpack Mineshafts & Monsters from curseforge (https://www.curseforge.com/minecraft/modpacks/mineshafts-monsters). Modpack version - 1.10.12 with Forge - 36.2.20. I downloaded the server pack and installed a forge server on my pc. The server is running with no problems. But when I try to join I get the message "Incomplete set of tags recieved from server. Please contact server operator." https://imgur.com/a/1ODXh7G.
Client log:
I tried to redownload all those mentioned mods manually and replace them but that didnt work. The server and the client both have the same mods, I copied them from one folder into the other to be sure. I dont know how to fix this problem.
