Product:
Cognos Analytics 11.1.7
Microsoft Windows 2019

Problem:

User can not login to CA11, they get a blank page or spinning icon.

Possible Solution:

Ensure the user URL they enter in the web browser end with / and not only /bi

Valid URL for Cognos:

http://servername.domain.com/ibmcognos/bi/

http://servername.domain.com/ibmcognos/bi/v1/disp/

NOT valid URL:

http://servername.domain.com/ibmcognos/bi

The last word in the URL is considered a file, that need to exist, in that folder (D:\Program Files\ibm\cognos\analytics\webcontent) – if the URL does not end with /.

 

 

Clear the cache in the users web browser or try a different web browser like chrome.

If it does not help, check the cognos server log file for more information: D:\Program Files\ibm\cognos\analytics\logs\cognosserver.log
