- Plesk Onyx for Windows
Plesk was successfully secured by clicking on Plesk > Tools & Settings > SSL/TLS Certificates > + Let's Encrypt ;
Certificates on IIS FTP bindings were not modified, as can be seen in Internet Information Services (IIS) Manager > Sites > <IP Address> > FTP SSL Settings :
There are subscriptions present on IP addresses, as reflected in Plesk > Tools & Settings > IP Addresses :
This is intended behavior: IIS allows to install different certificates on different IP addresses and since subscriptions are present on the IP address, bindings are not modified.
The certificate can be applied to FTP manually by taking following steps:
Navigate to Plesk > Tools & Settings > IP Addresses > <IP Address> ;
Select a certificate from the dropdown list in SSL/TLS certificate section:
Click Ok .
