So im trying to make a custom modpack and see that you need connectivity 3.3 or higher in order to use origins plus plus but no matter what version i download whether it be 4.2 all the way down to 3.3 it constantly says its not working

From what I can tell, you are using the Fabric file on Forge. There was a mistake in the mods.toml file for that version, so I would suggest trying the Forge file (https://www.curseforge.com/minecraft/mc-mods/origins-plus-plus/files/4476127) which I have checked and has the correct version range.

I have split the files to improve my ability to troubleshoot and manage dependencies, so sorry if there was any confusion.
