HCX upgrade fails with error: "Failed to upload bundle"

Products

• VMware HCX

Issue/Introduction

The upgrade bundle file may fail or timeout using the HCX Appliance Management UI (port 9443) with the below error message.

The upgrade bundle file (e.g. VMware-HCX-Connector-upgrade-bundle-4.11.#.#-########.tar.gz.sha256.sig) is not found in the HCX manager /tmp/upgrade/download directory.

Environment

VMware HCX

Cause

This issue occurs because an intermediary device, such as a proxy or firewall, is preventing the file transfer.

Resolution

Verify no proxy, firewall, or intermediary device is impacting the file upload between the local machine and HCX manager.

Troubleshooting Recommendations:

• Perform simultaneous packet captures on the HCX manager and local machine and inspect the TCP stream using a packet analyzer tool.
  
  OR
• Use the local machine web browser diagnostic tools (e.g Developer Tools) to verify the API POST response (found in Network Console) while attempting file upload.
