Problem Description

When attempting to power on the Druva Phoenix Backup Proxy, users may encounter the following error message:

“A general system error occurred: No connection could be made because the target machine actively refused it.”

Cause

This issue typically occurs when the VMware vCenter Workflow Manager Service is not running on the vCenter Server.

Option 1: Restart the Service Using vSphere Web Client

Log in to the vSphere Web Client using a vCenter Single Sign-On administrator account.
Navigate to:
Administration > Deployment > System Configuration
Click Nodes, select the vCenter Server Appliance node, and go to the Related Objects tab.
Locate the required service (e.g., VMware vCenter Workflow Manager), right-click it, and choose Start, Stop, or Restart as needed.

Option 2: Restart the Service Using Command Line

Using Command Prompt:

Open Command Prompt as Administrator:
- Click Start, type cmd, right-click Command Prompt, and select Run as administrator.
Run the following commands to restart the service:
net stop "VMware vCenter Workflow Manager"
net start "VMware vCenter Workflow Manager"
Alternative (Using sc commands):
sc stop "VMware vCenter Workflow Manager"
sc start "VMware vCenter Workflow Manager"

(Optional) Check Service Status:
sc query "VMware vCenter Workflow Manager"

📝 Note
- We recommend consulting VMware Administrator before restarting any services

Additional Notes:

Ensure you have appropriate administrative privileges before performing service operations.
If the issue persists after restarting the service, consider reviewing vCenter logs for further diagnostics or contact VMware Support.
