404 & NS_ERROR_CORRUPTED_CONTENT on public assets #37171
Description
Steps to reproduce the problem
I'm installing Mastodon on a Gentoo machine behind a Cloudlfare Tunnel.
- Install Mastodon using official guide
- Use OpenRC scripts from the Gentoo phackerlay repo https://data.gpo.zugaina.org/phackerlay/www-apps/mastodon-openrc/files/
- Use official but edited nginx.conf (I removed SSL bits because Cloudflare provides its own certificates and encryption)
- Try accessing web interface
Expected behaviour
Home page displaying correctly.
Actual behaviour
Browser shows a blank page with only the mastodon logo and title with 404s and NS_ERROR_CORRUPTED_CONTENT all over the console logs. Mastodon server-side logs show 404 for every other resource than /.

All the web ui files (/home/mastodon/**) are owned by the mastodon user and readable + traversable (+x) by all users.
All my other services work fine, including a PeerTube instance which runs with nginx.
