How to register access to download applications from Google Play in iptables?

Question

linux

Good afternoon!
I need to allow access on the Linux gateway only to download the application from the google play market. At the same time, access to the rest of the Internet should be closed.
Access is needed to a specific application - it is not necessary to give access to the entire store.
I tried to allow access to play.google.com and accounts.google.com , as well as a number of other domains that I pulled out via tcpdump, but nothing happened. Rather, the device gets access to the app store, but the app itself cannot be downloaded.

Answer 1

make a logging rule before the prohibiting rule - and see where the application breaks.
