Issue Same certificate in domain and subdomain

[Frank.P]

Windows 2012 with Plesk 17.5 I have one certificate created in main domain.

Certificated Included:
- domain.com
- www.domain.com
- mysubdomain1.domain.com

And all subdomain can access and list the own subdomain certificate and all certificated of main domain.

Last weekedn I migrate to Windows 2016 with same version of Plesk. And now I not work like Windows 2012. if I create in main domain a certificate, only that domain can access. All subdomain o detect any certificate.

I must clone the certificate from main domain to all subdomain,

Why?
Any suggestion to do ?

I go to IIS10 and set manualy into server ... but can I do that by plesk without duplicate certificate.
