- Plesk for Linux
On Plesk Multi Server management node, in Home > Tools & Settings > SSL Certificates, Let's Encrypt button is not available under
Certificates currently in use for securing plesk Server :
Feature request with id #EXTPMS-1234.
The feature will be implemented in future Plesk Multi Server updates. Please check Plesk release notes for announcements.
As a workaround, Plesk on a Management Node can be secured with another, Let's Encrypt SSL certificate via Tools & Settings > SSL Certificates.
If Let's Encrypt certificate is required, it can be requested manually using Certbot or other ACME clients or using DNS validation via "ZeroSSL" or "SSL for free" services.
