After upgrade of CA11, when you save the Cognos Configuration you get a error message.

Reset the certificates on the server where you have the error.

6. In the c11\configuration folder, rename ‘backup.xml’ to ‘cogstartup.xml’.
7. Open Cognos Configuration, save the configuration and start the services.

If needed – if it is only one CA11 that have issues, start with only change on that server.
