• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Issue Cannot install Let's encrypt SSL Certificate

Mafaldo

New Pleskian
Hi guys,

I have a hard time to issue the "Let's encrypt" certificate for my domainn smarterapps.io on plesk, altough it worked for another domain also hosted via plesk pocketnews.io

I have shared the problem already in lets encrypt forum and they told me following:


" All public visible name servers are *ui-dns.org name servers, so your “internal defined name server"

pocketnews.io NS ns1.pocketnews.io isn’t public visible / doesn’t exist / isn’t relevant.
TXT entry isn’t public visible -> Letsencrypt can’t check that -> you can’t create a certificate. Looks like in reality you use http validation, not dns validation." "It’s a Plesk problem, Plesk should use http validation, not dns validation."


Please find attached two screenshots from the DNS configuration of my two domains. Pocketnews.io where the SSL certificate runs without any problems and smarterapps.io where I cannot issue any certificate.

I run plesk on a Virtual Server Linux Level 1 (v1605.12) Hosting provider is Strato. Plesk Version: Plesk Obsidian v18.0.29_build1800200825.21 os_Ubuntu 18.04

Thanks in advance for any help.
