(Solved) 2 errors upon joining my server

[Raithion]

I've recently made a custom mod pack. It works fine on singleplayer, but I'm getting 2 different errors when trying to log into my new server:

 

- First, I get a Fatally Missing Registry Entries error. This shows the timeline from the server starting up, to me joining and getting the fatally missing registry entries error.

- Then after that, I keep getting an Internal Exception error. This shows the timeline from the server starting up, to me joining and getting the internal exception error instead.

The mods, config files, and scripts on my client are for the most part the same as my server's. The only exception being, I have a few client-side mods that I have removed from the server to prevent supposed crashing.Is anyone able to tell me what went wrong? I've searched for answers, but it seems to be a case-by-case basis where everyone has a different thing wrong with their server/modpack.

 

Edit: I've solved it myself. Turns out I'm an idiot, and the problem was my server not properly transferring the config files from my client.
