we are deploying VMs through vRA 7.5 in NSX 6.4.3 environment. What happens is the following: some VMs get deployed without problems and some get deployed but don't get network connectivity working and "guest OS customization timeout" happens. So deployment fails.
So when I check in vCenter, all VMs get connected to the same logical switch, get proper IP settings in Windows, but some cannot ping default gateway and cannot reach anything else outside their own network.
For example, 3 VMs deployed in the same network, deployment started within 2 minutes for each VM, they are running on the same ESXi host, connected to the same logical switch, and they all can ping each other and other VMs in the same network.
But some cannot ping their own gateway and cannot ping anything else outside their network. Any tips where to start with troubleshooting? It is the same VM template in question, so no differences between VMs.
