Opening the website with https shows a default placeholder page as given below:
“This is the placeholder for domain <domain name>. If you see this page after uploading site content you probably have not replaced the index.html file"

The above error is due to the legacy mode enabled in hosting settings and http and https docs are redirected to different folders and this needs to be disabled:
Login into Plesk panel
Then go to Subscriptions > Select the <domain name>
Hosting settings
Compatibility mode for legacy option (Separate SSL/TLS and non-SSL/TLS content)
To disable this option click on the blue tick color box
Then click on the OK button to save the changes you made.
