why are certain devices on my network having difficulties seeing the internet?

I can't understand this:
Suddenly my RasPi HTPC and my BD player (Netflix for non-smart TVs) can't ping outside my LAN. Everything else is fine, but on these 2 devices, no port 80 or 443 suddenly.
WTHeck?

Difficult to guess the reason as you have given absolutely no information about your setup.

Yikes, apologies.
AC86, 384.19, native IPv6, unbound (w/adblock and YT blocker), cake-qos, connmon, spdmerlin...
the devices in question get IP addresses, but can't establish comms to the outside world. Everything else connects and surfs just fine.

Actually, it seems the firmware can connect (it will update), but the app (netflix) is blocking.
I'm guessing it's a crypto library thing, and have reached out to the netflix app developer.
Sorry all.
If anyone knows how to get into the backend of a samsung BD player with the same issue, inbox me.
