After you add a second network interface card (NIC) to a vRealize Automation appliance, some vRealize Automation management interface pages fail to load properly.
You successfully add a second NIC using vCenter, and the following vRealize Automation management interface pages display errors instead of loading.
Thepage displays an error about an unresponsive script.
Thepage displays an error about failing to read network interface information.
Starting in version 7.3, the vRealize Automation appliance can support dual NICs. However, the engineering template on which the appliance is based prevents the management interface from working properly until you apply the solution.
After adding an additional NIC, restart the vRealize Automation appliance.
