Can't connect to homeassistant.local:8123 - no access via lan but works with Wi-Fi

I had this problem and I solved it. Very simple:

  1. In the user settings you must have advanced mode
  2. Go to Settings-Systems-Network-Configure network interfaces-End0-Ipv4 and set Automatic
  3. In the Network adapter section, select Adapter: end0 (Default)
    After that everything worked for me

I’ll answer myself. I wrote nonsense there. In fact, the problem is in the local DNS. Usually, names are linked to addresses by some external DNS service. In the local network, this is not the case and the Multicast DNS service is used https://en.wikipedia.org/wiki/Multicast_DNS. This service is supported by Windows-based devices, Apple-based devices, but Android supports this service in a limited way. Starting with version 8, and not all devices.
