Troubleshooting
Problem
User launches the Controller client. User is prompted to logon to the CAM (Cognos BI security) namespace. After typing in the username/password, an error appears.
In addition, if a user launches the Cognos Connection website (http://servername/ibmcognos), they will get prompted to logon to the CAM (Cognos BI security) namespace. After typing in the username/password, the same error appears.
Restarting IBM Cognos service does not solve the problem. There are no errors inside the 'cogserver.log' file.
Symptom
Error after authenticating to Cognos Connection website:

The IBM Cognos gateway is unable to connect to the IBM Cognos BI server. The server may be unavailable or the gateway may not be correctly configured.
Try again or contact your administrator.
