Access denied error when running site with SSL

Solution 1:

The Require SSL checkbox should have 3-option radio button for "Client Certificates". What have you selected there? If you have it set to Require, then it will require client authentication and if you don't specify a client certificate, it will give you the access denied. If you set it to ignore or accept, it will not be a fatal error if you don't specify client certificate.

Solution 2:

IIS is not gentle about its SSL requirements. When a request comes via a non-SSL connection for an SSL-required resource, it returns a 403 instead of redirecting to the SSL page.

Manually change the address in the bar to https:// should work.
