I’ve been using Droid48 forever. It’s perfect.

The evolution of the user-agent string isn’t exactly the W3C’s fault.

Use a Chromium browser to inspect the cert.

If anyone knows how to get Firefox to show a bad cert before loading the page, I’d love to know.

Assuming you’re the one adding HSTS, you’ll have to inspect the cert and/or view the content that is getting returned. On desktop Chromium you can type “thisisunsafe” to load a page even with HSTS. Not sure how to do it on mobile FF.

Would seem weird for it to be intercepting your domain’s traffic but not the rest of the internet.

Edit: just noticed you’re not even loading an SSL page. Are you using https in the URL?

Are you getting redirected to their captive portal?

Try this:

http://neverssl.com

If you’re sure you’ve got a DNS entry for the Pihole FQDN pointing at Traefik, open the dev panel in your browser (F12), switch it to the Network tab, and visit the pihole URL.

See if you get anything back and especially take note of the HTTP status codes.

Can you see the router and service in the Traefik dashboard and do they show any errors there?

I think you’re close.

You need to change service: pihole-rtr to service: pihole-svc.

Do I have to redefine all of the same information I did in my Traefik yml but in this separate config.yml?

No, you just need to reference it like you have. Define once, reference many.

No worries for the question. It’s not terribly intuitive.

The configs live on the Traefik server. In my static traefik.yml config I have the following providers section, which adds the file provider in addition to the docker provider which you likely already have:

providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false
  file:
    directory: /config
    watch: true

And in the /config folder mapped into the Traefik container I have several files for services external to docker. You can combine them or keep them separate since the watch: true setting tells it to read in all files (and it’s near instant when you create them, no need to restart Traefik).

Here is my homeassistant.yml in that folder (I have a separate VM running HASS outside of Docker/Traefik):

http:
  routers:
    homeassistant-rtr:
      entryPoints:
      - https
      service: homeassistant-svc
      rule: "Host(`home.example.com`)"
      tls:
        certResolver: examplecom-dns

  services:
    homeassistant-svc:
      loadBalancer:
        servers:
          - url: "http://hass1.internal.local:8123"

Hope this helps!

I use the Traefik file provider for this.

https://doc.traefik.io/traefik/providers/file/

It picks up all my .yml configs in the watched folder which define the routers and services external to Docker.

I know plenty account SNI already, but thanks. You might want to study more yourself, since we’re being condescending.

So now your ISP sees all of your queries instead of CF. (Assuming the cloudflared option is using DoH)

I’ll trust Cloudflare over Comcast/AT&T/etc. any day of the week.

I believe you. I’m just saying their non-firewalls (i.e., switches and APs) don’t have that limitation.

My firewall is a Fortigate 60F.

I would never use their firewalls/gateways, but their switches are pretty good for the price and their APs are decent (although tbh after 3 generations my next AP will likely be an enterprise Aruba).

That said, I still use Unifi in docker, everything is up to date, and nothing is requiring a sign-in to the cloud. Am I missing something? If it’s just the firewalls, then I’m not surprised since I’ve never been remotely tempted to use them, but it sure isn’t all of their devices.

In that case, if CF is taking to Traefik and not the actual origin server, you just need to forget about the origin certs altogether and use LE certs in Traefik.

If you, Traefik, and your origin server are on the same network, then it’s going to be one hop regardless of whether you’re hitting the Traefik proxy or the origin server. If Traefik is serving up the origin server’s cert and not the LE cert, then Traefik is misconfigured to pass through instead of proxy, but I’m still not sure that’s the case as it’s almost harder to configure it that way than the correct way as a proxy.

What IP:port is your origin server listening on, what IP:port is Traefik listening on, and how is Traefik configured to reach the origin server?

You said Traefik is getting certs from Cloudflare, but do you mean it’s getting Let’s Encrypt certs using a CF DNS challenge? And if that is the case, then your browser should trust the Traefik endpoint since LE certs are publicly trusted.

Are you sure you’re hitting Traefik when you get a cert warning? You need to update your internal DNS if not.

Oh I get plenty of chances to use 420. But I think you might be missing the joke. 😁

I like returning 418 instead of 404 or 403 on the files the script kiddies are hunting for on my web servers. I’m sure it does nothing but I’d like to think I’ve wasted some of their time at least once.
