Server crashes before it starts

Whenever I try and load up my server with the Craft of the Titans 2 modpack it always crashes. It goes from starting to crashed. Also my friend who's also tried starting up a server with that pack is able to but whenever we load in it's extremely laggy. Although when I play on single player it doesn't lag at all. My servers don't crash while loading up other modpacks so I don't know why its not working. Here's my log https://mclo.gs/40jBoyG
