The discussion highlights a bug where videos fail to load on published Discourse pages, displaying only a black background placeholder. Don reports that this issue persists regardless of whether videos are uploaded via the standard composer or the Discourse Video Plugin. Notably, no errors appear in the browser console or system logs, making the cause difficult to diagnose. Later, mad revives the thread to ask if a solution was ever found, noting that they are experiencing the same problem on a recently updated, vanilla Discourse instance.
Hello 
Seems the videos not appears on Published page. We tried it with uploading the videos through the composer as usual and also tried with Discourse Video Plugin which doesn’t work too.
There is no error in console or /logs.
On published page only appears black background on the video placeholder.
Thank you 
I see this is an old post, but did you find a solution for this @Don ? I just updated a pretty vanilla discourse instance, and we also struggle with embedded video on published pages…
