Under certain rare conditions, you may lose connectivity to your managed Linux or Windows workload VMs. Try the following steps:
From your Public Cloud (AWS or Microsoft Azure)
Ensure that all ports on the VM, including those managed by NSX Cloud, the OS firewall (Microsoft Windows or IPTables), and NSX-T Data Center are properly configured in order to allow traffic,
For example, to allow ping to a VM, the following needs to be properly configured:
- Attempt resolving the issue by logging in to the VM using SSH or other methods, for example, the Serial Console in Microsoft Azure.
- You can reboot the locked out VM.
- If you still cannot access the VM, then attach a secondary NIC to the workload VM from which to access that workload VM.
