Problem Modded Server Crashing on Startup

[Frnkln41]

I am making a modded server for a custom modpack. However, partway through startup it crashes with the following error:


[17:50:45] [Server thread/ERROR] [FML]: Fatal errors were detected during the transition from CONSTRUCTING to PREINITIALIZATION. Loading cannot continue


This is a pastebin of the log: https://pastebin.com/J7Yy13G4
This is a list of all of the mods I am using on the server: https://pastebin.com/u6axsji3

Did you read your own log?

If you're going to do a custom mod pack you need to be prepared to do some work, read logs, add a few mods at the time and so on.

Check line 668 and down.

Also it looks like you have client side mods on your server, read the log and fix that.

Sorry for the really late reply, haven't checked this in a long time, but is there a way to see which ones are the client side mods?

"Wrong side: SERVER" would be a good place to start
