Issue/Introduction

The error: "Error loading Site Pairings Error: Unable to process HCX inventory details" is received while trying to access the site pairing in HCX while logged in with an Active Directory (AD) User Account.

Cause

The error is seen when a user is logged in using credentials other than "[email protected]" or "[email protected]", typically an AD User Account.

Resolution

The logged-in user needs to be a part of the vSphere role mapping designated in the management UI of HCX.
If tried Logging in with the [email protected]  credential, the error could be resolved.

For successful login with AD credentials, the below-mentioned points are to be taken care at:

a. On-prem :

Ensure the OnPrem HCX Manager's vSphere role mapping includes an AD Group that the target AD user account is a part of. This can be checked by following the below-given steps:

1. Login to the OnPrem HCX Manager VAMI - https://{HCX-FQDN}:9443
2. Click Configuration
3. Click vSphere Role Mapping

b. VMware Cloud: 

Ensure the SDDC vCenter's CloudAdminGroup includes an AD group that the target AD user account is a part of.
This documentation provides information on adding the AD group appropriately via an APIExplorer:
