SOLVED: Certbot cannot verify domain


My domain is: and

I ran this command:sudo certbot --apache --staging

It produced this output:
Type: connection
Detail: Fetching

Type: connection
Detail: Fetching

My web server is (include version): Apache/2.4.18 (Ubuntu)

The operating system my web server runs on is (include version): ubuntu 16.04

My hosting provider, if applicable, is: AWS

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

If I refresh the page quickly while certbot is verifying, I can view the verifications. Even when I go through a proxy to somewhere in germany I can view the verifications. But certbot keeps failing. Any ideas?

#2 is advertising an AAAA resource record with an IPv6 address, but when connecting to that IPv6 address, no one is answering: i.e., a time out.

You should either fix your IPv6 connectivity or delete the AAAA record from your hostnames.

By the way, your www subdomain doesn’t have an AAAA-record, so that should have worked… Perhaps you deleted it already? :stuck_out_tongue:


You are the best! that was exactly it!

Thank you!


Yeah. and had the same AAAA record before.
