Cannot connect to HA via wifi


I’m new here and I have a problem with my HA accessibility.
I running the HA on an RPi 3+ and it is connected to the router via ethernet cable. Today I installed the duckdns and when I try to connect to it via home wifi, it is not accessible.
Via ethernet, and outer networks (mobile internet) the connection works fine.
The port forwarding: outer 443 to inner 8123.

Please help!
Thanks in advance!
