I am absolutely stumped with my config; requests are reaching Traefik, but even though the config is fully parsed, it doesn't seem to be detecting the host to route to, and is returning a 404. I really cannot understand why. Can anyone see what is wrong?

For reference, the domain \*.domain.com is an Azure hosted domain that resolves to \<\< internal-ip-of-backend \>\> (the IP where Traefik is running on my local net). When I visit [rp.domain.com](http://rp.domain.com) (where the dashboard should be) or [nas.domain.com](http://nas.domain.com), I correctly get a Letsencrypt staging cert presented, so Traefik is obviously firing

data/config.yml:

```auto
http:
  routers:
    dashboard:
      rule: "Host(`rp.domain.com`) && PathPrefix(`/api`, `/dashboard`, `/debug`)"
      service: api@internal
      tls:
          certResolver: dns
    qnap:
      rule: "Host (`nas.domain.com`)"
      middlewares:
        - https-redirect
      tls:
        certResolver: dns
      service: nas

Does anyone have any bright ideas? Thank you very much!

For a test, remove the dynamic `insecureSkipVerify` and add a global one in `traefik.yml`:

```auto
## Static configuration
serversTransport:
  insecureSkipVerify: true

```

Remove this, it’s made for dashboard on `:8080`:

```auto
api:
  insecure: true

```

And you can place the http-to-https redirect and TLS globally on the `entrypoint`, see [simple Traefik example](https://github.com/bluepuma77/traefik-best-practice/tree/main/docker-traefik-dashboard-letsencrypt).

Thanks for the reply. Done that, and the dashboard URL still 404s, but the nas URL now gives an internal server error, which I guess at least means its trying.

This appears in the log:  
level=debug msg="'500 Internal Server Error' caused by: tls: failed to verify certificate: x509: cannot validate certificate for \<\< internal-ip-of-backend \>\> because it doesn't contain any IP SANs"

Which I presume means that my insecureSkipVerify isn't working? I put it as a top level item in traefik.yml right under the entry points definition:

```auto
serversTransports:
  insecureSkipVerify: true

```

Any thoughts?

</div>

It's according to the [doc](https://doc.traefik.io/traefik/routing/overview/#insecureskipverify). Did you remove the other transport from the service?

It’s complaining that you use https with an IP address, instead of a matching hostname. But I would assume that should be fixed with working `insecureskipverify`.

So I've created a DNS name for the backend, [nasreal.domain.com](http://nasreal.domain.com) and updated the configs so they look like the below.

The error is now different, which I assume means I haven't set up insecureSkipVerify correctly?

level=debug msg="'500 Internal Server Error' caused by: tls: failed to verify certificate: x509: certificate is not valid for any names, but wanted to match [nasreal.domain.com](http://nasreal.domain.com)"

Also, the dashboard URL ([rp.domain.com](http://rp.domain.com)) still 404s

Thanks again!
