DVR Access Failure: trust anchor for certification path not found

This sounds like an issue with the root certificates on the device. I’m not an Android expert by any means but my first question would be if you have any kind of extra security or other software that might mess with the certificates on the device.

What's the version number?

I didn’t do anything, and it started working after a few days. Not sure what happened.
