Hi there,
For what it's worth, I've been seeing very inconsistent results with my own HLS / SSL implementation. I'm also using DigiCert as my CA, as is Amazon's CloudFront service.
What I find a bit odd is that other HTTPS requests to the server complete without issue, but should I feed https into the roVideoScreen (even with code exactly as yours) the https calls to the m3u8 fail (apparently prior to request, because there no log noise about them). When I remove https from the m3u8, and the TS chunks within are over https, the same result:
request failure: -3 An unexpected problem (but not server timeout or HTTP error) has been detected.
If assets are sent over HTTP, things succeed. The most baffling part is that my HTTPS requests (mp4 video assets, https/m3u8, https/TS chunks) were working fine on Friday, and without any code changes they no longer succeed on Monday.
