Error Issuing Certificate

[JuergenAuer]

Hi @miche11e

@miche11e

My domain is ranchmarketcleaners.com

I ran Let’s Encrypt from my cPanel hosting account.

It produced this output:
"There was a problem processing your request

• Error issuing certificate
• Failed to issue certificate
• Updating challenge for mail.ranchmarketcleaners.com: acme: error code 400 “urn:ietf:params:acme:error:dns”: DNS problem: NXDOMAIN looking up A

that's simple. You use cPanel, cPanel creates a certificate with a mail subdomain.

But checking that subdomain - https://check-your-website.server-daten.de/?q=mail.ranchmarketcleaners.com

Host	T	IP-Address	is auth.	∑ Queries	∑ Timeout
mail.ranchmarketcleaners.com		Name Error	yes	1	0
www.mail.ranchmarketcleaners.com		Name Error	yes	1	0

There is nothing defined, so Letsencrypt can't check the validation file.

So you have two options:

• Check your cPanel, there you have an option to uncheck the mail subdomain (or)
• if possible and if you want / need such a mail subdomain, add a mail subdomain in your DNS setup, so mail.ranchmarketcleaners.com has the same ip address (same A-record) as your main domain ranchmarketcleaners.com. Then recheck your domain, there should be the A-record visible. Then try to create a certificate.
