I've played on the server a few hours ago with my friend, but now I can't get back on it. First it was crashing, but I figured out it's because it was taking a long time to start up. Now it starts and I try to join immediately after, but I can't get on. It won't connect and then when I check the server it's offline even though it's been only like a minute or so... I don't know what to do 
Btw the modpack is Magiculture 2 and I downloaded it from twitch

This is the log when it just crashes after starting for more than 10min: https://mclo.gs/p0I1akG
