Issue/Introduction

Symptoms:
  • Issue started after upgrading VCD to 10.5 version.
  • Viewing vApp properties displays red banner at the top of the page with the error:

[ UUID ] The address <IP> did not belong to any known host.

  • When viewing the VMs inside each vApp, the same error is displayed.
  • The VMs work as expected.
  • The logs doesn't show any reference to the UUID or the alert.


Environment

VMware Cloud Director 10.x

Cause

The IP in the alert can be identified as a DNS IP address for an OVDC network, which has a space character at the end of the address resulting in the issue. 

Resolution

To resolve the issue, remove the space character in the DNS fields on the OVDC networks connected to the vApps.
Refer the documentation for how to edit the DNS settings of the OVDC network.
