Adding a subdomain to the current certificate

Traefik Traefik v2
1

The other day I successfully added a subdomain to traefik, but it's still giving me a warning about an invalid certificate.

I have already tried to search the docs, but can't figure out if there is something I need to do in order to add this new domain to the current certificate.

Can someone please point me in the right direction?

I am still trying to resolve this and so far, on the dashboard, the container and subdomain show up has having TLS turned on, but it still returns an invalid certificate.

The way I got it to work was by using the file config. It has two servers configured, the HomeAssistant one is working, but the video-conference one is not.

  [http.routers]
    [http.routers.homeassistant]
      entryPoints = ["https"]
      rule = "Host(`home.domain.tld`)"
      service = "homeassistant"
      [http.routers.homeassistant.tls]
    [http.routers.meet]
      entryPoints = ["https"]
      rule = "Host(`meet.domain.tld`)"
      service = "meet"
      [http.routers.meet.tls]

  [http.services]
    [http.services.homeassistant]

        url = "http://192.168.1.10:8123"
        passHostHeader = true

And there is an error in the log I can't quite understand:
