The "Site is unavailable" error appears during the Unity PCA login

Core Issue

This error can occur due to one of these reasons:

  • The error can occur when a subscriber browses to http://:/ciscopca and when Internet connection issues, a PIX Firewall or Secure Sockets Layer (SSL) restrictions are not factors. A possible cause is that the Internet Services Application Programming Interface (ISAPI) redirection filter failed to load.

  • The Tomcat service is stopped.

  • The Internet Information Server (IIS) and Tomcat integration are not configured correctly.


To resolve these issues, choose from one of these options:

Unity Version

Unity 4.x
