Resolution

Changes to resolve the issue
1. reset password

2. changed the user privilege on UIM

3. exclude the non-standard port, in this case 8880, to 80 

Then, reverted the port 8880 since it is used by our standard UIM 3rd party alarm integrations. its possible (1) and (2) resolved the initial problem.

Alarms are now processing, :UPDATE, NEW, CLOSED on UIM
