Certbot - Renewal Fails due to IPV6 records

In access logs I don’t even see that anybody hit my server. More details here: https://github.com/certbot/certbot/issues/4764

My domain is: wiki.betacoda.cono.org.ua (CNAME)

I ran this command: certbot renew --config-dir /home/letsencrypt/conf --work-dir /home/letsencrypt/work --logs-dir /home/letsencrypt/logs

It produced this output:

My web server is (include version): www-servers/nginx 1.11.3-r100

The operating system my web server runs on is (include version): Gentoo Base System release 2.3

My hosting provider, if applicable, is: Hetzner

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

Your FQDN resolves to IPv4 and IPv6 addresses.
LetsEncrypt prefers IPv6.
Ensure you have IPv6 access or remove the IPv6 from the DNS resolution.
