This article resolve port miss-configuration when using a custom port for the VMware vCenter Workflow Manager.


This issue occurs when the VMware vCenter Workflow Manager service is configured to use custom ports (Default ports used by the service are 8088 and 19999).


To resolve this issue, update the vpxd.cfg file on vCenter Server to use custom ports when communicating with the VMware Workflow Manager:
  1. Open the vpxd.cfg file in a plain text editor.
    • Windows installed vCenter Server - C:\ProgramData\VMware\VMware VirtualCenter\
    • vCenter Server Appliance - /etc/vmware-vpx/

  2. Add these entries to the vpxd.cfg file:


  3. Restart the vCenter Server Service. For more information, see How to stop, start, or restart vCenter Server 6.x services (2109881).

Additional Information

To increase logging on the Workflow Manager:
  1. Open the file in a plain text editor.
    • Windows installed vCenter Server - C:\Program Files\VMware\vCenter Server\workflow\conf\
    • vCenter Server Appliance - /etc/vmware/vmware-vpx-workflow/conf/

  2. Edit these lines setting them to Debug:


    For example:
