No, certificate only contains www. it is multidomain certificate but for a specific domain, it has only www. So that, i believe this is the reason why this error occurs. Is there any way to eliminate this certificate error ???

 

Reflecting upon the OSI model, it's important to understand that layer 6 (SSL) happens before layer 7 (HTTP), and that the two are, for the most part, independent and oblivious of one another. What you're seeing is the result of an SSL handshake that performs badly (because the cert doesn't match the requested host name), and before you've actually decrypted the traffic to be able to process HTTP URLs. The only way to deal with this is to include "unlumenkul.com" in a new multi-domain certificate.
