Have you ever thought that your Cognos Connection session has already expired and you still receive an authentication error stating that the user is already connected to Cognos? If so, then you should:
· clear your web browser cache and rerun the Cognos report
· close your browser, open it again, and restart your Cognos 8 session
· attempt to log on to Cognos 8 again, reauthenticate your credentials, and then click the back button in your browser to return to the portal. Run the report again.
