I have a pi-Hole serving my network. Since a long time I have seen a lot of requests to chunks.memfault.com from my phone. They where all blocked. I thought it was because of my old Samsung phone. But now I switched to another Android phone and the requests are still there. I installed NetGuard to see which app makes the requests, but none of them are. There is an entry for memfault.com but there is no app attached, only sni. So that makes me wonder if Android itself makes calls to this URL?

Or is there another way I can find out which part of my phone makes these calls?

    I just looked at my Pihole and I don’t see any requests for this domain in the last 24 hrs. 4 people with android phones on my network. Maybe best to block it for now? Could be from an app you have running in the background too, if you transfered data to the new phone.

    Edit: I remember when I noticed that my ASUS routers are pinging google for connectivity checks. Fortunately, those were configurable. (RT-AX58U and RT-AX58U v2.)

    Could be an IoT device pinging memfault with a keepalive or connectivity check. These are usually hard coded, but, as you said it yourself, absolutely blockable.

      Thanks, it’s coming from my phone since pi-Hole matches it to my phone and NetGuard (firewall app) sees it originating from my phone as well.
