 This error is caused when there's a clock/time difference between ESXi host(s) and the management machine where the deployment commands for Arc resource bridge are being executed. To resolve this issue, turn on NTP time sync on the ESXi host(s) and confirm that the management machine is also synced to NTP, then try the deployment again.

+This error occurs when the vSphere network segment resolves to multiple networks due to multiple vSphere network segments having the same name that is specified in the error.

 ### Arc resource bridge status is disconnected
 
 When running the initial Arc-enabled VMware onboarding script, you were prompted to provide a vSphere account. This account is stored locally within the Arc resource bridge as an encrypted Kubernetes secret. The account is used to allow the Arc resource bridge to interact with vCenter. If your Arc resource bridge status is disconnected, this may be due to the vSphere account stored locally within the resource bridge being expired. You must update the credentials within Arc resource bridge and for Arc-enabled VMware by [following the updating vSphere account credentials instructions](/azure/azure-arc/vmware-vsphere/administer-arc-vmware#updating-the-vsphere-account-credentials-using-a-new-password-or-a-new-vsphere-account-after-onboarding).
