Apologies if this should be posted somewhere else.
I have had this TV for about 7 years and have never had this pop up before. About a month ago, I bought a router that uses OpenWRT. With that, I setup up Adguard and specifically one of the lists that is supposed to block devices from phoning home.
Am I nuts thinking that this pop up is due to the TV not being able to offload what has been recorded? How would I check that?


Yup. And it’s worth noting that my two smart TVs are the noisiest devices on my network, by far. Like it’s not even close. In a heavy day of doing nothing but doomscrolling and casual browsing, my phone may get 1700-2000 blocked requests. My smart TVs typically hit 5500-6000 blocked requests each.
Which, when you do the math, comes out to a failed request every ~15 seconds. Which means they’re probably attempting to reach the server, getting blocked, timing out after ~15 seconds, and then retrying. If they were logging each failed attempt as an error and never purging their old logs, I can see how it would slowly but surely fill their storage space.
