It’s a CORS issue. It’s already fixed in Khatru, but I haven’t had time to update Haven yet. I also want to clean up my changes and add caching to these CORS headers directly in khatru. If nostr:npub1utx00neqgqln72j22kej3ux7803c2k986henvvha4thuwfkper4s7r50e8 
doesn’t get to it first, I’ll try to update Haven this weekend. For now, you can enforce the CORS headers in Nginx at the location level (see below). However, I don’t recommend this from a security perspective.

With CORS headers in place, Cloudflare works smoothly on top of Nginx/Docker. Just be careful not to serve videos through Cloudflare as it’s against their ToS. I’ve been there before with my personal Mastodon instance and migrating media to a proper CDN wasn't one of my top 10 favourite activities.
