Home Assistant URL section disappeared

Hello everyone,

I am very new to Home Assistant and therefore also very new to this forum.
So far I am enjoying Home Assistant very much and have managed to solve most issues I ran into by intensive Googling. This one, sadly, I cannot find a solution for.

I have been experimenting with remote access to my Home Assistant server though Tailscale. I have managed to be able to access my HA in my mobile browser and was trying (unsuccesfully…) to get the companion app to work as well when not connected to my home network. I tried this by adding this to my configuration.yaml file:

    homeassistant: 
        internal_url: http://<ip_address>:8123
        external_url: http://<MagicDNS_name>:8123

While this was in my configuration.yaml file, I was unable to edit the ‘Home Assistant URL’ section in the frontend System>Network settings, which made sense, but was also unable to edit any other General Settings like my Time Zone, Language, etc.

After realizing it didn’t work, I deleted it from my configuration.yaml file again, and then the complete ‘Home Assistant URL’ section in the System>Network settings disappeared, and I also received the following errors:

Unable to set up dependencies of ‘default_config’. Setup failed for dependencies: [‘zeroconf’]

Could anyone help me with this issue of the disappeared settings section and explain to me what the errors might mean?

Did you remove default_config from your configuration.yaml?

You may need to put it back. OR at least put back the separate ones you actually are using. Since you posted this, I suggest just putting default_config back.

Thanks for responding so quickly.
I never removed or tampered with default_config, that remains unchanged.
It just says default_config:

And then it’s just empty, always has been.
