I have a certificate that I created that includes an IPv6 hostname. The renewal fails saying it could not connect to the IPv6 address for verification. I’ve tested the IPv6 hostname connectivity using ssllabs.com so I know the server is responding. Is this an issue on the letsencrypt.org end?
Please fill out the fields below so we can help you better.
My domain is: soft1-v6.discoverypatterns.com
I ran this command: ./certbot-auto renew
It produced this output: Attempting to renew cert from /etc/letsencrypt/renewal/soft1.discoverypatterns.com.conf produced an unexpected error: Failed authorization procedure. soft1-v6.discoverypatterns.com (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Failed to connect to [2607:f0d0:1b02:33::4]:443 for tls-sni-01 challenge. Skipping.
My operating system is (include version): centos6.9
My web server is (include version): 2.2.15
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): no
