Another 3 months has past and I needed to renew my certs. The previous method for taking care of NycNyne is still a relatively simple one liner, but matthannan.net continues to be a nightmare. Well, a hassle, anyway.
I went with the links in the Part 2 of this series and was mightily struggling with the first one. Wanna know why? I was updating the TXT record at NameCheap, not CloudFlare! I happened to recall that I moved my DNS servers to CloudFlare a while back.
Anyway, the third link ran like a charm. I am going to put the command, run from a local instance of Debian, here, but all credit goes to the guy in Part 2.
sudo ./certbot-auto certonly --server https://acme-v02.api.letsencrypt.org/directory --manual --preferred-challenges dns -d *.matthannan.net -d matthannan.net
I want to also remind my three months from now self about this little gem, that is displayed after you run this code:
To obtain a new or tweaked version of this certificate in the future, simply run certbot-auto again. To non-interactively renew *all* of your certificates, run:
sudo certbot-auto renew
