I use AdGuard DOH DNS on Chrome in Android ( DNS-over-HTTPS )

They can be set from Chrome settings like this:

AdGuard DOH works if the phone uses mobile data, but not if I browse through the home Wi-Fi. The phone connects to the Wi-Fi, but I can't browse the internet.

Browsing the net I managed to understand that it is a fairly common problem, and that it would have to do with port 853 but I'm not so sure, the only thing I am sure of is that I have not been able to find a solution.

The fact is that if it doesn't work only at home with the router, it is a problem that comes from the latter.

P.S. The problem remains the same even using other TP-Link modems/routers such as Archer VR2800v or VR1200v.
