I'm not exactly sure when this started happening, but Amazon Video, YouTube, and Plex all no longer work if PiHole is on.
What's really weird is that if I turn off the pihole for 30s, open each app once, they load correctly and then I turn the pihole back on, everything works fine until I put the TV to sleep. When it wakes up those apps no longer work again.
I do have auto app updates turned off to try and avoid the apps updating and then breaking, but it looks like they have have updated themselves anyways or something else happened.
What I don't understand is that when I check the PiHole logs when opening one of the problem apps, I don't see any blocked requests besides the ones from the TV itself to
samsungcloudsolution (and it spams that 24/7 so nothing new there), so I can't figure out what it is that is causing this behavior. I'm just not sure how to go about debugging this and would appreciate any help.
