I don’t know if this is related, but I can’t use F-Droid on Android 6 since it does not contain the Let’s Encrypt cert without rooting the device, and it seems like F-Droid has stopped using the cross-signed version or maybe it’s Let’s Encrypt itself has stopped cross-signing? This happened a few months ago.
I’d wager the root CA certificates on the device are expired since it hasn’t been updated in ages. So it can’t trust certs signed with the new root CAs.

Android 6 was released almost exactly ten years ago. What device are you still running that it still runs on Android 6, if you don’t mind me asking?
ASUS Tablet. I like it. Probably will replace with Linux tablet at some point.
At this point, why not just root it? There are public exploits for Android 6 vulnerabilities, it’s not like you’d lose any security.
Time. I think I will at some point unless I buy and flash a Linux tablet first.
