It is becoming harder and harder to troubleshoot which apps talk what to which servers because all off them, including OS, talk something all the time. Back in the day if user told me they have a problem accessing some Internet content I would instruct them to close all the applications and start to dump their traffic on firewall and proxy. There wouldn't be any traffic from their IP address. Then, when they started the application I would see if traffic goes through proxy or directly through firewall, and make adjustments, like putting destination domain on an exclusion list in proxy or destination ip and port on an exclusion list in firewall. Nowadays, Windows 10 without any applications started sends hundreds of requests per minute to dozens of IPs. Something respects global proxy settings, something not. I guess Android is even worse.
