Server Crash

Uh hi, so my server keeps crashing because I was trying to update my server mods by downloading the newer versions, but they said that there are multiple files and its crashing so I deleted them and when I redownloaded the mods, they crashed again and told me to delete it. 0>0

Yeah, so I deleted the files that I needed to delete, now its telling me to download a certain Pehkui, but when I download the forge version it doesn't work and it basically did nothing and I got the same thing, but when I downloaded the other version (which is not forge) it wants me to delete and download the same version but a different one, I've been doing this for the past 10 minutes, do I have to delete the server and then make a new one? https://mclo.gs/4fGcIJ8
