Whatsmydnsserver.com never works when using pi-hole

Ever since I started using Pi-Hole, the whatsmydnsserver.com has never worked with it. I have seen a couple of posts here and in the github issues forum that suggests it works for other people.

I have tried using whatsmydnsserver.com when using the standard version and the docker version and with different upstream DNS servers set, but it never works.

Does it work for you and does anybody have any idea why it does not work for me?

The site doesn't load for me at all. What information are you seeking on that site? Perhaps an alternate site can provide it.

It's supposed to show you what DNS server you used to access the site. It does not seem to work when using pi-hole.

It's especially useful for testing if a VPN connection is working correctly.

I do not know of any similar sites.

Pi-hole doesn't have that domain on it's default blocklists. It resolves to IP as it should.

The site it quite broken:

Try http (no https) and it's actual web site domain.

So, if you know the owner of this site tell them:

Enable TLS/SSL so https:// works, and fix their redirect from bare to www. as it's not correct.

Use https://www.whatsmydns.net/

That's a propagation checker.

Okay, it seems that the site isn't working at all, using pi-hole or not. I've used it in the past, so hopefully it will start working again some time. Cheers.
