Error "Unable to Modify the Listen Port for the Current Admin Connection" Encountered When Editing a Listen Port in Policy Manager

Products

• CA API Gateway

Issue/Introduction

When editing a Listen Port via Policy Manager, the following error may be encountered upon saving the changes to the Listen Port:

Unable to modify the listen port for the current admin connection

Environment

All supported versions of the API Gateway

Cause

This error occurs because the port is in use for the current administrative connection via Policy Manager. Changes cannot be saved to a Listen Port when it is currently open for the active Policy Manager session. For example: if connecting on port 8443 via Policy Manager, then changes cannot be made to Listen Port 8443.

Resolution

To resolve the issue, perform the following steps:

1. Disconnect from the current Policy Manager session.
2. Connect to the Gateway again with Policy Manager but this time using a different port number than the port needing to be edited.
   • Example: If changes couldn't be made to 8443, then try making the changes while connecting over port 9443.
   • Gateway host connection should be in the format of <GatewayIP/Hostname>:<Port#>

Additional Information
