Issue Securing Plesk with LetsEncrypt Error

[sall10]

Hello,

i moved to a new host also with Plesk Obsidian 18.0.29 Update1 / CentOS Linux 7.8.2003 (Core)‬ and tried to Secure the Plesk Admin Panel with a LetsEncrypt Cert. But when requesting the Cert under Tools&Settings - SSL/TLS Certificates + LetsEncrypt i get this error message:

Error: Could not issue a Let's Encrypt SSL/TLS certificate for XYZ.stratoserver.net.

Failed to connect to the Let's Encrypt server

Boulder: The Let's Encrypt CA

.
Please try again later or report the issue to support.
Details

Could not obtain directory: cURL error 6: Could not resolve host: acme-v02.api.letsencrypt.org; Unknown error (see libcurl - Error Codes)

How can i get my Admin Panel Secured ??

Thank You!

Hi @sall10,

Please confirm whether you have registered an A record for the hostname?

Hi TravisB,

Thanks for the reply. Yes, confirm to have registered A record for the hostname:

nslookup xyz.stratoserver.net

Name: xyz.stratoserver.net
Address: 85.x.x.x

Rebooted also the server several times, and tried again, still get the error Could not obtain directory: cURL error 6: Could not resolve host: acme-v02.api.letsencrypt.org; Unknown error
