The ZyXel Keenetic Start router is blocking some Play Store pages via Wi-Fi, what's the problem ??

Question

network hardware

The problem is this:
There is a Samsung A5 phone, when you enter Google Play via Wi-Fi, the main page works fine when you try to download some applications (I will repeat some), it does not download, but writes that the connection time has expired, and the same thing happens when you try go to the list of installed.
This problem only appears when trying to do this with the ZyXel Keenetic Start Router.
When connecting to other Wi-Fi points, everything is fine, everything is also fine when connecting the Internet via a SIM card.
I can’t find this malicious setting that blocks the play market.

Is Yandex/Sky DNS enabled? If "Yes", I would advise you to disable and check the work.
