Clearing up a little confusion with Let's Encrypt's DNS challenges

I love that lead to some fun... So I moved eagerly to Let's Encrypt when the tooling supported Windows reasonably well, and set myself up with a certificate with multiple SANs authenticated via their "HTTP proofs" mechanism, and it all worked fine, despite it being a bit of a pain that I had to expose port 80 for sites I only wanted accessible via port 443.

But I realised recently that they now offer wildcard certs that would make my life simpler, and that there is now decent support for DNS-based proof-of-ownership. So recently I tried moving my server over to this model – and there was a bit of friction. Entirely PEBCAK though – so I'm writing this down for the next time I forget how DNS works 😉

Bonus chatter: I can't let my 200th post pass without comment...

When I wrote my first blog post here ** in February 2014 I definitely did not imagine still being at it 200 posts and five-and-a-bit years later. Originally I set myself a challenge of writing something once a week for a year, just to see if I could motivate myself to do it.

Honestly, I didn't really think I'd manage to keep it up for the entire twelve months, let alone still be here now – but somehow it's become part of my routine. I may have scaled down to a post every fortnight, as kids and other responsibilities took over more of my time, but the process of making myself notes about issues I encounter as I'm working, and then writing them up when I have free moments has become part of my working life now...
