The vmware-service.log shows:

vCenter vpxd logs show: 
2025-04-09T16:42:49.360Z error vpxd[41485] [Originator@6876 sub=User opID=7a0c4405] Failed to authenticate user <userID>

(**No domain is shown for the userID)

Cause

Login fails because login does not pass the domain with the userID for authentication.
 
The user ID should be input using format userid@domain. The logs for this instance show: 
<userID>
But it should show: 
<userID@domain>

Resolution

The credential used to add the vCenter asset source should be changed or re-created to use the format userid@domain.
