Example: yourserver.com instead of www.yourserver.com.Java strips "www" from URL to get just the host/domain name (this is the common implementation). If the website is not configured to accept traffic without "www", we won't be able to pull the certificate.ResolutionContact the website administrator to allow traffic without "www".
