Symptom

When trying to access the Home Assistant user interface, you see the message:

• You're about to give https://somekey.ui.nabu.casa/ access to your Home Assistant instance. Logging in with Trusted Networks. Login aborted: Your computer is not allowed.

Cause

This message indicates that you have trusted networks configured in the configuration.yaml file. Due to the way the Remote UI is set up, you cannot use trusted_networks over the cloud URL.

Resolution

There's two ways to resolve this. Option 1 is to not use trusted networks at all. Option 2 is to use trusted networks, but only locally.

Option 1: Do not use trusted_networks

1. Open your configuration.yaml file.

2. Delete the entire type: trusted_networks section.

   homeassistant:
   auth_providers:
      - type: trusted_networks
        trusted_networks:
         - 192.168.0.0/24

3. If you like, set up Multi-factor authentication.

4. To apply the new network settings, restart Home Assistant.

5. Log in with your credentials and multi-factor authentication.

Option 2: Keep using trusted_networks, but only locally

1. Open your configuration.yaml file.

2. Make sure that in addition to type: trusted_networks, you also have a type: homeassistant section.

   homeassistant:
   auth_providers:
      - type: homeassistant
      - type: trusted_networks
        trusted_networks:
         - 192.168.0.0/24

3. If you like, set up multi-factor authentication.

4. To apply the new network settings, restart Home Assistant.

5. In the login screen, choose Home Assistant Local.

   • Log in with your credentials and multi-factor authentication.
