Bunny Embed Iframe
If the iframe shows "✅ Loaded" but the video area is black, the embed page loaded but the CDN media requests inside it are failing. Check the Network tab for 403 responses on vz-ddc791ad-cd3.b-cdn.net.
What to look for in Network tab
- Request to
iframe.mediadelivery.net/embed/... — should be 200 - Request to
vz-ddc791ad-cd3.b-cdn.net/.../playlist.m3u8 — check status (200 = OK, 403 = Referer blocked) - Request to
vz-ddc791ad-cd3.b-cdn.net/.../thumbnail.jpg — check status - For any 403 request, check the Referer request header — is it present or missing?
