I get the same type of error like Simon Willison below, in certain feeds. I did not realize it was a Django problem, until now.
When I find another example in a feed, I’ll post it here. Thank you, Samuel.
I just read this, but I don’t get that error. We already have CORS headers, I’ll investigate.
I see it on my iPhone (17, iOS 26.1) with this feed (as an example): https://www.youtube.com/watch?v=yoGBk-X7r1E
Thanks,

Me too, on iOS, with YouTube feeds. For example, with this feed: Andrew Huberman
For me, the iOS issues seemed to start the same time that YouTube started requiring a referrer be sent (see YouTube API Services - Required Minimum Functionality | Google for Developers) - I found that all the videos I’d embedded on my websites with referrerpolicy=“no-referrer” in the iframe properties started failing with the 153 error, and when I replaced it with referrerpolicy=“strict-origin-when-cross-origin” they started working again.
Not sure that’s what’s happening here (I can’t inspect the iframe in the iOS app) but the symptoms and timing made me wonder.
Some more discussion of the issue and some related factors here: https://stackoverflow.com/questions/79802987/youtube-error-153-video-player-configuration-error-when-embedding-youtube-video
I’ve created a ticket for @Dejal to take a look at, I believe we should be able to set those headers in the app.
Got a PR that fixes it, just waiting on review and submission to the app store.
Thank you.
Just FYI: the bug also exists in NewsBlur using the latest Firefox on MacOS. However not in Safari.
This has not been my experience. I use Newsblur on two Macs, an older one on Mac OS 12.7.6 and a newer one on 15.7.2. Both have Firefox 145.0.2, and embedded YouTube videos work fine in Newsblur in both. (Haven’t tried the Mac desktop app.)
Could be a config difference?
You are right.
Error 153 shows up even outside of Newsblur.
