My server keeps crashing

I've been trying for hours to set up a server so I can play with my friends but every time I try to boot the server it just crashes. I've tried to look at the logs but I can't figure out what's the issue, please help me, I don't want to use something like Radmin.

My logs: https://mclo.gs/f17KDPz

It seems the issue is coming from Chickencore but I have no idea on how to fix it.

So, after trying a lot to fix it I managed to figure out the issue was one mod missing and Mekanism, but I really want to use Mekanism and I don't know what to do
