Got certificates for sub domains, but not top domain

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: pquirk.com

I ran this command:sudo certbot --apache

It produced this output:Obtaining a new certificate
Performing the following challenges:
http-01 challenge for www.pquirk.com

Cleaning up challenges
Failed authorization procedure. www.pquirk.com (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://www.pquirk.com/.well-known/acme-challenge/jjWdZVjlqtaGw3YOctb0KkoLOIQHoDKjbFh5kR1eCJI: “\n\n\n<meta charset=“UTF-8”>\n<meta name=“viewport” content=“width=device-width, initial-scale=1”>\n<link”

IMPORTANT NOTES:

My web server is (include version):Apache2

The operating system my web server runs on is (include version):Ubuntu 18.04.1 LTS

My hosting provider, if applicable, is:Me

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

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.28.0

Additional notes: I was able to obtain valid certificates for my sub-domains, which are cloud.pquirk.com and history.pquirk.com using this utility. They exist on a virtual server that is also serving pquirk.com, so I am at a loss.

Check that you don't have multiple virtual hosts with www.pquirk.com for a ServerName or ServerAlias:

apachectl -t -D DUMP_VHOSTS

Both show: “Assessment failed: No secure protocols supported”
https://www.ssllabs.com/ssltest/analyze.html?d=pquirk.com
https://www.ssllabs.com/ssltest/analyze.html?d=www.pquirk.com

Well, that’s interesting; it shows a problem with cloud.pquirk.com, but that certificate is fine; here’s the output:

AH00526: Syntax error on line 54 of /etc/apache2/sites-enabled/cloud.pquirk.com.conf:
SSLCertificateFile: file ‘/etc/letsencrypt/live/cloud.pquirk.com/fullchain.pem’ does not exist or is empty
Action ‘-t -D DUMP_VHOSTS’ failed.
The Apache error log may have more information.

Did you run it as root?

No, I’m kinda dumb that way. Thanks for the advice, I did that, and found an original wordpress.conf file that was created before I went with virtual servers, and that was messing things up. Got my certificate now, thank you so much for the help!
