I just noticed that certbot has failed the renewal of the SSL certificate on my site.
When running certbot manually I was able to renew the certificate for 1: example.com but when trying 2: www.example.com I get the error
Failed authorization procedure. www.example.com (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://www.example.com/.well-known/acme-challenge/Yz4RezbUvNFiGMoUi__MV5-XpmQ3tD2DwSeO4cpxWrw [2607:f8b0:400f:800::2013]: "<!DOCTYPE html>\n<html lang=en>\n <meta charset=utf-8>\n <meta name=viewport content=\"initial-scale=1, minimum-scale=1, width=dev"
I also get a 404 error when visiting www.example.com in my browser, but http(s)://example.com works fine.
I'm running the ubuntu droplet from digitalocean with apache.
Any thoughts?
Ok turns out I'm really, really stupid. I had messed up the DNS records.
