Issue/Introduction

Symptoms:
  • Connecting to the VMware vSphere Data Protection (VDP) appliance from the Web Client fails.
  • You see the error:

    The most recent request has been rejected by the server. The most common cause for this error is that the times on the VDP appliance and your SSO server are not in sync.

  • This issue occurs when your vCenter Server and ESXi hosts are configured for NTP and are syncing from the same NTP.

    Note: For more information, see the NTP Configuration section in the VMware vSphere Data Protection Administration Guide.


Environment

VMware vSphere Data Protection 5.5.x
VMware vSphere Data Protection 5.1.x

Cause

This issue occurs when the offset between the ESXi host (hosting the VDP Appliance) and the vCenter Server/Single Sign On becomes too high.

Resolution

To resolve this issue, use the NTP Query utility program ntpq to remotely query the ESX/ESXi host's ntpd service. Run the command ntpq -d IP Address and check the offset values.
If the offset values are high (values closer to 0.00 are best), take steps to reduce the offset. For example:

Note: This list of steps is not exhaustive.
Additional Information
To change the configured time zone in VDP, see the Changing vSphere Data Protection Configuration section in the vSphere Data Protection administration guide 5.1/5.5.
