SSL is configured without an external URL or internal URL

Configuration

The latest update to 2024.10.1 has made me aware that my SSL is configured without an external URL or internal URL

I have been using Let`s encrypt with certbot to certify my external domain (from ddns). I have configured my router to DNAT the incoming traffic from wan to the local address and the local port and this works seamlessly regardless whether I am accessing the router from wan or lan.

So I guess the remark is somehow related to that. I however could not figure out, what should I do, or what it is the fix.

When going to the suggested configuration through the UI, it says my configuration is configured in configuration.yaml, so the UI is locked.

When I look into my yaml, it says:

http:
  # Secrets are defined in the file secrets.yaml
  ###api_password: !secret http_password
  ssl_certificate: /home/hass/letsencrypt/config/live/<domain>/fullchain.pem
  ssl_key: /home/hass/letsencrypt/config/live/<domain>/privkey.pem
  # Uncomment this if you are using SSL/TLS, running in Docker container, etc.
  #base_url: <domain>:<port>
  ip_ban_enabled: True
  login_attempts_threshold: 5

Apparently base_url is an ancient artifact, which has been defunct for a long time. In the forum I found people talking about internal_url and external_url options, but no one has seemed to have clue what to do with them and when looking at the current documentation for http: section on HA web, these config options seem to be defunct too.

Since I have not seen this error before, I guess it is fairly new, but so seem the web documentation.

Does anyone know, what is the actual problem, and how to fix it?

Kudos for checking the docs, you’re in the top ten percentile :rofl:
However, like me you found a different reference than the one intended. It is this external url that the warning is about:

The “Remote access” doc unfortunately say basically only “go to the settings and change it”.

But the settings in my case are locked because I have apparently something in configuration.yaml. Which is true, but I do not see how to go without it.

4

If you have the yaml version, you need to set them there, or remove the yaml bits from configuration.yaml to get them editable in the ui. The docs have unfortunately removed the bits how to do so in yaml. I had them there long ago so I looked in my github history. It should be here in yaml:

homeassistant:
  external_url: ....

If all ui configurable settings are gone there, the ui is available again.

5

This is strange. I tried to put both external_url and internal_url in the config, but HA complained that these are unknown options and basically bailed out.

6

That would indicate they removed the possibility. But if so, you should be able to use the ui? Or are there other UI settings still in yaml under homeassistant?

In the UI I can find this:

which says that UI is disabled (so I cannot change “Internet” edit box).

If I switch Local network to manual, it just displays similar box for it, but I cannot change this one too.

In the configuration.yaml I only have paths to TLS certificates, which I believe I need in order to have the web server using them.

This is what I have in my Network settings. Ignore the invalid warning - it’ll work just fine once you click past the chrome (or other browser) warning that you are trying to access an http site over https:

This is they http: section in my yaml. Note that the base_url is commented out, so it might as well not be there (it’s a remnant from when it was migrated to UI which I never removed)

http:
  #base_url: https://myinstance.duckdns.org/:8123
  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem
  ip_ban_enabled: true
  login_attempts_threshold: 5

I do not, nor have I ever had, have any entries mentioning external_url: under the homeassistant: key. Everything should go under the http section. Your config seems identical to mine except for the path. Can you try and move the certs to the ssl folder?

PS- if you’re using DuckDns, I’m 99% sure you don’t need a separate Let’s Encrypt & certbot Addon/Integration/whatever it is you’re running. Let’s Encrypt is built into the Duckdns addon already.

When I tried these options, I put them under http: section, not homeassistant: as suggested by @Edwin_D, and for both, HA complained they are not recognized.

For what concerns the placement of the key and certificate, I have it this way, because certbot runs as shell_command with HA privileges, so it is convenient to have all it needs in HA home directory (I am running HA Core).

I am not running duckdns.org as a DDNS. The thing in my screenshot is just a stub, created by HA.

Anyway, my problem is not with accessing the HA web page either from internal or from external network - both work exactly as they should. The only “problem” is HA complaining about something and me having no clue what is the problem and what is HA expecting instead.

Internal and external url only makes sense if the program can detect your connection and only the companion apps can do that.
The companion apps have that setting already, so my guess is that all those settings ever did or do is making the companion app able to autofill those two settings.

11

I think the external one might also be for oauth to provide a callback in the authentication of integrations. Wht I think you should focus on is why the section is disabled in the UI. I’m pretty sure that was because of things defined in yaml below homeassistant. Are there things there that can also be set in the ui?

I found this:

What worked for me was the part of “enable the advanced settings in your profile” … didn’t know that exists … then there appears the filed for the external URL in the network config.

I also have the same issue as the original poster. I am able to access the ‘Home Assistant URL’ section but no way to change anything.
Any idea how to fix the issue in the yellow box?
I have the following code in my configuration file:

http:
  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem
  ip_ban_enabled: true
  login_attempts_threshold: 5
  # Cloudflare tunnel
  use_x_forwarded_for: true
  trusted_proxies:
    - 172.30.33.0/24 #Allow requests from the local cloudflared process

Comment the http section out, restart HA (beware, now you need to use http:// instead of https://), make the changes in the UI, uncomment the http section, restart HA

Commented out and restarted HA. Logged in via http://homeassistant.local:8123.
The issue is still there. Can’t set the URLS from the UI.

Indeed, it is the keys under homeassistant: you have to comment out.
