Does my Lemmy instance support video streaming? tchncs shows ❌ Error: Failed to fetch (aeharding.github.io)

Many Lemmy instances are misconfigured, which can break progressive video streaming and even basic image loading in strange ways. The latest default lemmy-ansible config handles this correctly, but many instances use custom proxy setups that cause issues. This tool will check that:

  • ✅ The instance supports HTTP range requests for proper video streaming
  • ✅ CORS headers are properly set for API and pictrs media

The instance result shows:

Any updates on this? I mean, it's not a critical issue by any means, but to my understanding (without knowing the specifics of your hosting setup) it could be an easy fix.
