If i am correct, Chaos Awakens (assuming you mean the OreSpawn successor mods) was rejected from CurseForge by CurseForge, meaning it's not on curseforge, hence we cannot add Chaos Awakens on the website. While it is currently on Aternos, you probably can't actually download it to your server anymore. I'll inform the team and ask them to remove the mod.
Ah thanks. It still can be downloaded to the server though somehow.
