So I made a modpack for me and my friends, so that we can play together on the server. Making the mod pack wasn't that tough because I could retrace my mistakes (trials&errors). But I tried making a server, it spawns the world and everything but when I try to connect, get a glimpse of the surroundings and inventory before getting kicked and getting a message "Internal server error", so if anyone could help me out, either by teaching/showing me or by making the server for me. I would be very grateful thank you
