I came here through Google and found another thread that says IPv6-only domains are supported as of July 2016. Still doesn’t work for me. All software from the Ubuntu repository is up to date.
My domain is:
a domain that is only available through IPv6 and has no A record, just AAAA
I ran this command:
letsencrypt certonly --webroot -n -w /var/www/certbot -d “$DOMAIN”
It produced this output:
Failed authorization procedure. $DOMAIN (http-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Could not connect to $DOMAIN IMPORTANT NOTES: - The following errors were reported by the server: Domain: $DOMAIN Type: connection Detail: Could not connect to $DOMAIN To fix these errors, please make sure that your domain name was entered correctly and the DNS A record(s) for that domain contain(s) the right IP address. Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you're using the webroot plugin, you should also verify that you are serving files from the webroot path you provided.
My operating system is (include version):
Ubuntu Server 16.04
My web server is (include version):
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
