Get SSL certificate from server (Site URL). You can refer below URL
    https://www.shellhacks.com/get-ssl-certificate-from-server-site-url-export-download/

Use Java's keytool utility to add downloaded certificate to Java's keystore
    keytool -importcert -file <path-of-certificate> -keystore <keystore-file> -alias <certificate-alias>
    i.e. keytool -importcert -file E:\certs\some-site.cer -keystore "E:\sw\jdk1.8.0_112\jre\lib\security\cacerts" -alias "some-site"

Now you will be able to access HTTPS URLs
