My friends and I have a server that is intended to be used for a customized and not pre-curated Modpack on 1.20.1. We've uploaded the appropriate files (more than once) to the server information/server files and confirmed they were installed. Once we attempted to log into the server, we were met with a "incompatible FML" error; the error then explains that ALL of our mods were not on the server files and we needed to remove them from our game to be able to access the server.
We've confirmed already that the server has more than enough RAM to run the modpack, and have used all available tutorial videos on uploading the mods to the server, but nothing is working. Please help!
