The website also had certificate issue for which i permanently stored exception.What can be the reasons for this error? Any help would be appreciated

Answer 1

The error message indicates that you are trying to establish an SSL/TLS connection using a port on the server that speaks HTTP and not HTTP S . Make sure you have the correct port - usually 443 for HTTPS.
