I had a 1.7 setup that had been working for months now. The certificate needed to be renewed but it failed. I don't have IPV6 and Checking [https://letsdebug.net/ca1.devhaus.com/172955](https://letsdebug.net/ca1.devhaus.com/172955) says that it is timing out.

I am able to hit the server

```auto
$ curl -v http://ca1.devhaus.com

This is with the alpine image. The non-alpine one appears to work.
