Hi, I currently have a minecraft server dedicated (mxtserv), I'm using the modpack Chroma Technology on Minecraft 1.12 and when I try to loggin on the server the server stops and I didn't know why ...
There is my crash report : https://pastebin.com/1DkJPhcC
And the server log : https://pastebin.com/3C4gcbCv
I'm a newbie with minecraft servers, I'm getting crazy with it.
Thanks in advance for help,
