Issue/Introduction

Attempting to redeploy or resync the HCX Interconnect (IX) appliance fails with errors similar to below:

• "Interconnect Service workflow OvfUpload failed "
• "Appliance Config is incomplete, please check credentials"
• "Cannot complete login due to an incorrect user name or password."
• "Peer site connectivity down"

Environment

Cause

The most common cause for these errors is reachability between the peered HCX sites. 

Resolution

Review the following items to ensure there is connectivity between the peered sites in both directions:

• Check the HCX Manager Dashboard to verify vCenter is showing healthy. 
• If needed, reauthenticate to vCenter. 

If vCenter is showing healthy and authentication is successful, open a ticket with the VMC on AWS Global Support team. 
Include the following information:

• Organization ID
• SDDC ID
• External HCX version
• VMC HCX version
• Date and time of redeploy or resync error
