I also tried the modpack THE 1.7.10. It might have conflicting mods or mods that are not meant for online but it always launches but then closes do you guys want me to post the server start up logs ?

I hope i'm posting this in the right place but me and my friend have been looking for a modpack and we have found one but it has no server file. I don't really know how to organize myself a server but i know how to start one. I want to know if theres a mod pack that has Blood magic, Tinkers Construct, and a ME system and more mods but that have a downloadable server file . I've tried starting a server on F.T.B.T Modpack but Forge just wont launch at all. I'm un sure if its because some of the mods on the modpack are not suited for multiplayer. I need help
