"Operation canceled due to an unexpected error" reported when checking for updates via online repository in VCDA

Products

• VMware Cloud Director Availability - Disaster Recovery 4.x
• VMware Cloud Director

Issue/Introduction

The update check through the online repository in VMware Cloud Director Availability fails with the error message: “Operation canceled due to an unexpected error.”

The appliance does not list any updates even though a newer version is available.

Connectivity tests (e.g., curl) from the appliance to the default repository URL (for example: https://packages-prod.broadcom.com) fail.

 

 

Environment

 VMware Cloud Director Availability 4.7.3.1

Cause

This issue occurs when the VMware Cloud Director Availability appliance does not have outbound HTTPS (port 443) connectivity to the official Broadcom repository URL or its equivalent.

Resolution

Verify and restore network connectivity:

• From the appliance shell, run:

  curl -v https://packages-prod.broadcom.com

• If the connection fails, check:

  • Outbound firewall rules allow HTTPS (port 443) from the appliance.

  • DNS resolution is working for the repository host.

  • No network routing issues (default gateway, proxy settings).

• Refer to the network requirements for VCDA appliances

After connectivity is confirmed, retry the update check:

• In the appliance UI, go to Settings --> About → Check for updates.

• The repository should now be reachable, and updates listed.
