The Unitrends appliance cannot communicate with the virtual failover client

The appliance cannot perform virtual restores if it cannot communicate with the virtual failover client. After the first failed attempt to perform a restore, the appliance places the VFC in a Halted state. After several minutes, it attempts the restore again. After three failed attempts, the status of the VFC becomes Invalid, and it remains in a halted state until you delete it.

The most likely reason the appliance cannot communicate with the VFC is that there is a problem with the network settings. To resolve this problem, you must delete the VFC (see Deleting a virtual failover client) and create a new one with valid network settings (see Setting up a virtual failover client).

When assigning network settings to the new VFC, consider the following:

The IP address must be unique.
The IP address must have the same subnet as the hypervisor on which the VFC resides.
You must assign the VFC the same gateway as the hypervisor on which the VFC resides.
