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:
discuss.tchncs.de ❌ Error: Failed to fetch
i have added some headers (most interesting perhaps slice) - however arte currently times out when testing, aeharding does not seem to present opengraph stuff to test, peertube seemed to work normally before my adjustments
playing back an uploaded video didnt look like it was sliced however it played without showing any obvious errors anywhere
i have added
proxy_hide_header Access-Control-Allow-Origin;which seems to help with that reflected origin
