I have the domain nue2lax.com with a let’s encrypt certificate up and running on my root server. However, following the same procedure in Plesk let’s encrypt extension for my subdomain, I get the error stated on the output section below.
The domain and subdomain are both targeted to the right IP address in the A records. The domain is also reachable, but I would like to get a certificate for this subdomain as well. I’m not sure how to read the error message though. I thought I have the DNS A Records set correctly.
Help is very appreciated! Thank you a lot!
My domain is: webmail.nue2lax.com
I ran this command: plesk extension
It produced this output:
Error: Let’s Encrypt SSL certificate installation failed: Failed letsencrypt execution: Failed authorization procedure. webmail.nue2lax.com (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://webmail.nue2lax.com/.well-known/acme-challenge/F1gXnVcvBrdabfP0odBGO0OJUlx_sD51FCEZDxl2CJY: "<!DOCTYPE HTML PUBLIC “-//IETF//DTD HTML 2.0//EN”>
