Try removing toomuchtnt

 

It looks like it's calling a client function, which will crash a dedicated server (but works in single player, since the server/client both exist)

Also stop using 1.8, it's outdated.

unfortunately most mods are 1.8

Then you're going to have to check with the author to see if they have a jar for the dedicated server
