Server crashes when loading mods

Hello,

I'm trying to play on my modded server but, when it tries to load a certain mod, Security Craft, it instantly crashes and I have no idea why. Here is the log: https://mclo.gs/yLnaAXl Also, I've done the mod combinations before and it was fine. I don't know whether it is the forge version or the mod version. Please let me know what to do.

Thanks!

I saw that security craft failed to load but didn't know what to do about it though. Thankfully, I was actually able to figure it out. Thank you for replying.
