im using Plesk Obsidian 18.0.29 Update1 / Centos 7 and try to request for my plesk panel an LetsEncrypt Certificate. When requesting the Cert i get the 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 https://acme-v02.api.letsencrypt.org .
Please try again later or report the issue to support.
Could not obtain directory: cURL error 6: Could not resolve host: acme-v02.api.letsencrypt.org; Unknown error (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)
Any Idea how to solve this?
