Issue/Introduction

SSL with forms based authentication, explicit proxy, and cannot connect to the virtual host
Browser Error:  Page cannot be displayed

Resolution

When running into this issue, users will experience a connection error or see "Page Cannot Be Displayed."

With forms or redirect based authentication, the virtual host must be set to a hostname which resolves to the proxy's IP address. However, when using these types of authentication with SSL (HTTPS) there also must be an HTTPS service created for port 443:

In the management console, browse to Services > Service Ports. Create a new service port with the following settings:

Protocol: HTTPS
IP: either or the IP that your virtual host resolves to
Port: 443
Enabled: yes
Attributes: Explicit
Keyring: The keyring you created for the virtual host
SSL Versions: SSLv2v3TLSv1
CA-Cert Lists:

This will allow the proxy to listen for the HTTPS connection that clients make when being redirected to the virtual host.
