Server is stopping after start

Hi , i want to play a modded server and it worked fine (even tho she couldn't join because missing regrestries or something) i could join. then i was waiting for her and i went offline and when i tried to start it up it was starting up and then stopping right after. here is the log: https://mclo.gs/EBO3O5X

also ik i dont have the lib thing for decocrat but i removed decocraft from the mod list but it was still showing up
