An administrator is tasked to bring up a VMware Cloud Foundation (VCF) instance.

The error message “Gateway IP Address for Management is not contactable” indicates an issue with network connectivity. During the deployment validation process in VMware Cloud Foundation (VCF), VMware Cloud Builder checks that all specified IP addresses, including the management gateway, are reachable. If the management gateway IP cannot be contacted, it typically means there’s a network configuration issue, such as incorrect routing, subnet mask, or an unreachable gateway, which prevents proper connectivity.
