Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: www.youandideas.com

I ran this command: certbot --nginx --redirect -d www.youandideas.com -d youandideas.com -m admin@youandideas.com --agree-tos --no-eff-email

It produced this output: Requesting a certificate for www.youandideas.com and youandideas.com

Certbot failed to authenticate some domains (authenticator: nginx). The Certific ate Authority reported these problems:
Domain: youandideas.com
Type: unauthorized
Detail: 2600:1901:0:e8db::: Invalid response from https://youandideas.com:443/ .well-known/acme-challenge/l_KArgAXn0RggrFM_2vJuVDLgHCzvZkedmKm7v_5GmU: 404

Domain: www.youandideas.com
Type: unauthorized

Hint: The Certificate Authority failed to verify the temporary nginx configurati on changes made by Certbot. Ensure the listed domains point to this nginx server and that it is accessible from the internet.

Hi @A66, and welcome to the LE community forum :slight_smile:

Please confirm that your site works via both IPv6 and IPv4:

Name:      youandideas.com
Addresses: 2600:1901:0:e8db::

How do I go about doing that?

Do you have access to any system on the Internet that has both IPv6 and IPv4?
If not, there may be some online tools that can check for you.


Your domain's IPv6/AAAA record is pointing somewhere other than your nginx server.

You could try logging into your DNS control panel and removing the AAAA record.


When you get that sorted out, you might also want to correct the "mixed content" on the site:

curl -4 youandideas.com | grep
<link rel='dns-prefetch' href='//' />
<link rel="alternate" type="application/rss+xml" title="youandideas &raquo; Feed" href="" />
<link rel="alternate" type="application/rss+xml" title="youandideas &raquo; Comments Feed" href="" />
