BMT-MD-6629 Unable to find a running Query Service at the configured dispatcher

Product:
Cognos Analytic 11.0.6
Microsoft Windows 2012 R2 Server

Problem:
Error when publish a dynamic cube from cube designer.

Error message:
BMT-MD-6629 Unable to find a running Query Service at the configured dispatcher: servername

Possible solution:
Check the server name in Cognos Configuration.
They must be in lower case, so they match the server name you see in Cognos Connection – Administration – status tab – System view.

Change all server name references for dispatcher URI for external applications to be in lower case. Save the configuration and retry the publish in Cube Designer.
