My domain is: calculator.360-biz.com
My web server is (include version): Apache HTTPD 2.4.66-8
The operating system my web server runs on is (include version): RHEL 7.6
I can login to a root shell on my machine (yes or no, or I don’t know): yes
I ran this command:
sudo certbot certonly --manual --preferred-challenges dns-01 -d calculator.360-biz.com
and successfully obtained a cert, but once set up in my Apache server, Chrome reports an incorrect subjectAlternativeName, which is true. The certificate was issued for the root domain (360-biz.com), and not the subdomain.
I’m managing the DNS with GoDaddy and I suppose the error might be here. In order for the challenge to work, I had to shorten the TXT values to “_acme-challenge.calculator” and <certbot_value> instead of the full domain, otherwise it was failing.
This wouldn’t be painful except that the http-01 challenge is also not working. Any ideas?
