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
