The error is seen when user is logged in using credentials other than "[email protected]" or "[email protected]", typically an AD User Account.
The logged in user needs to be a part of the vSphere role mapping designated in the management UI of HCX.

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:
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:
