The page you are trying to access is secured with Secure Sockets Layer (SSL).
Most likely causes:
Secure Sockets Layer (SSL) is enabled for the URL requested.
The page request was made over HTTP, but the server requires the request from a secure channel that uses HTTPS.
Things you can try:
Browse to the URL over a secure channel by using the "https:" prefix instead of "http:".
If the Web site does not have an SSL certificate or should not require HTTPS, disable the setting.
Verify the SSL Settings in IIS Manager by connecting to the server, site, application or page and opening the SSL Settings feature.
Verify the configuration/system.webserver/security/access@sslFlags attribute at the server, site, application, or page level.
This error means that the requested Web page requires SSL. Try to browse to the same URL, but use "https:" instead of "http:".
