Environment

Release : 9.4

Component : API GTW ENTERPRISE MANAGER

Cause

Message Processing was not permitted on the port where the GMU was attempting to communicate.

Resolution

1. Confirm if the listen port attempting to be used did not have the Published Service Message checked 
     which is required for the GMU to function as it calls the /restman service. It must to be Enabled.
2. If for security need to limited on the port being used then create a new port.
3. Check the Published Service Message, and from the Advanced Tab -> Service Resolution -> 
   Associate Port with published service -> Pick the Restman service. 

Notes :

- The port that is hard coded in the GMU is port 8443 as that is the standard port in the Gateway product.

- The port being used can be changed by adding -p in the command.
