The valid domain's SSL certificate replaced by the automatic provision of Let's Encrypt certificate after modifying service plan to use Let's encrypt certificates.
The following message can be found in
CONFIG_TEXT: DEBUG [extension/letsencrypt] Domain is secured by valid (not Let's Encrypt) certificate, do not keep it secured.
This is a Plesk bug with ID #EXTLETSENC-656 which is planned to be fixed in future Plesk updates.
As a workaround, the necessary certificate should be manually selected in Domains > example.com > Hosting Settings.
