Can not expand tm1 instance in PAW

Planning Analytics Workspace 74
Microsoft Windows 2019 Server


Can not expand proven_techniques in databases under modeling tools in Planning Analytics Workspace.

Other TM1 instance work.

Possible solution:

The TM1 instance HTTPportnumber is not open in the firewall.

PAW uses REST API, HTTPportnumber, to communicate with the TM1 instances.

Change to a port you now the firewall let trough, by edit the tm1s.cfg file.


Save the TM1S.CFG file and try again.

PAW have access to the TM1 Admin service, therefor the TM1 instance is listed in the tree.
