Cause

The issue occurs when the vpxuser password is out of sync with the vCenter Server database and the password on the host or the password is manually modified. The vpxuser account is created by vCenter Server when adding an ESX host. VMware does not recommend modifying the vpxuser account.

Resolution

To resolve this issue, resynchronize the password with the vCenter Server database. The host reconnects without the error on the Summary tab.
 
Note: Do not remove the host from the Inventory. When an ESX/ESXi host is removed from the vCenter Server Inventory, virtual machines are removed from their respective folders, performance data for the host is lost, and any Distributed Virtual Switch configurations on the host needs to be reconfigured.
 
To resynchronize the password with the vCenter Server database:
  1. Right-click the ESXi host and click Disconnect.
  2. Reconnect the host and enter the root password when prompted.

    Note: For more information, see the Disconnecting and Reconnecting a Host section in the vCenter Server and Host Management Guide.
When reconnected, the virtual machines are placed in a folder in VMs and Templates view and appear in the Hosts and Clusters view under the hosts they are registered to. Reorganize virtual machines into their correct folders.
