We tried to change the clientCAMURI to use the cognosisapi.dll.
The login to TM1 and BI still works as expected, but there is no change in C3.
Furthermore, we realized that there is some strange error in the browser console when the login page is loading.
I'm uploading this, as well as the other config settings below:
Cognos BI uses port 8080, while Canvas uses 8095.
