The CurseForge API rejected the request
What it looks like in your log
Access to https://api.curseforge.com is forbidden
What causes it
The CurseForge API returned forbidden: the API key is missing or invalid, or a dollar sign in the key was swallowed by the environment file.
How to fix it
Issue a key from the CurseForge developer console and set it cleanly. In docker-compose files every $ in the key must be doubled as $$.
