Nextcloud apps stopped working

The Apps download menu hangs when it is fetching the apps, nothing pops in the docker logs or Nextcloud’s own logs. I am running behind Cloudflare and I may have assumed that the CSP causes this problem but the network log and console says something else.

All I can see are the already installed apps. Tried disabling Cloudflare routing, nothing changed.

Additional info:

  • I am running Nextcloud behind a nginx reverse proxy
