Custom Modpack Server Issue

[sliggybiggy]

So I made a modpack, and it works, however, I also made a server package, that doesn't work.
I followed some tutorials on the internet and none of them fixed the issue.

Here's my log

Y'know, except that one reply where I told not to use Java 10, but java 8. Oh wait, multiple posts over the past few months.
