Playback stops after failed retries with 403
What version of Hls.js are you using?
1.5.14
What browser (including version) are you using?
Chrome 129.0.6668.72 and Safari 18.0
What OS (including version) are you using?
macOS 15.0
Test stream
No response
Configuration
{}
Additional player setup steps
Using https://hlsjs.video-dev.org/demo/ for a minimal reproducer and has to be an actual live stream so a 403 response can be sent for a very short period of time and then a 200/206 returned once it's available
Checklist
- [X] The issue observed is not already reported by searching on Github under https://github.com/video-dev/hls.js/issues
- [X] The issue occurs in the stable client (latest release) on https://hlsjs.video-dev.org/demo and not just on my page
- [X] The issue occurs in the latest client (main branch) on https://hlsjs-dev.video-dev.org/demo and not just on my page
- [X] The stream has correct Access-Control-Allow-Origin headers (CORS)
- [X] There are no network errors such as 404s in the browser console when trying to play the stream
Steps to reproduce
- Open
- Load an EVENT or LIVE stream
- Start playback
- Observe that if a segment returns a 403 because it's not yet available, then 6 retries happen immediately and the stream playback fails, but if a slight delay happened between retries, then they would be successful and the playback could continue
Expected behaviour
There would be a slight delay between the retries so it was more meaningful. This is the behavior of both Safari and Video.js
What actually happened?
Immediate retries that all fail and the playback stops

27.447 | A network error occurred: fragLoadError
(you can see that it almost failed the first time but one of the last retries worked and then the second time all of the retries failed and the playback was stopped)

Hi @daveisfera. Have you tried dev ( https://hlsjs-dev.video-dev.org/demo/)? Is the behavior the same?
The media internals are not useful in this case (hls.js is deciding what to load, not the browser's decoder/renderer). We need hls.js console logs (config: debug: true) to understand the error/retry attempts being made. Please update the description.

Yes, I tried the dev site with the same outcome. I included the console output and if I'm understanding that test page correctly, then debug: true is on by default so that should be in the output.
that should be in the output.

There should be more than just errors. Maybe you're filtering some of the console output?
Here are some related issues about the retry policy for 4xx errors that may contain some helpful information:
- #5647
- #6323
Yes, I had noticed those issues, but those are a 404 response and I understand that S3 will respond with a 403 for both a missing file and a permission denied, so the 403 is very similar to a 404 in this case, but there technically is a difference and the short retry time of HLS.js is causing a problem here that is handled correctly by Safari and Video.js.
Here's the logs from a run that ran into the issue: hlsjs.video-dev.org-1729030566007.log
