Server decoding error, need help

Threw together my own modpack to play with friends, worked for 5 versions and I just tried adding a few new mods and 2 datapacks. Singleplayer runs perfectly fine but it seems something is up with the server, I redownloaded all mods to the server and removed the datapacks to see if they were the issue. Does anyone know how to help?
