Question In what route/path install plesk onix ssl certificates?

[lepe]

Hello

I am trying enable HPKP for my ssl certificates adding wrong code in htacces generated in ssh and I can´t calculate the right sha256 for the public key because I receive errors due to wrong route path.
I followed this tutorial trying many options (.key, .pem, .crs, .crt) adding like openssl x509 -in www_mywebsite_fr.crt -pubkey -noout | openssl rsa -pubin -outform der | openssl dgst -sha256 -binary | openssl enc -base64 but I received next error:

Error opening Certificate www_mywebsite_fr.crt

I checked in etc/ssl/certs and here only i can see "localhost.crt" and I am searching one of my two websites certificates www_mysite_fr.crt

Where is located route/path of certficates installed from plesk onix in Centos 7 and apache 2.4.6 ?

NOTE: I installed certificates from plesk onix 17.5.3
