Management channel to Transport Node vmwNsxTDataCenterTransportNodeName (vmwNsxTDataCenterTransportNodeAddress) is down for 5 minutes. Action required: Ensure there is network connectivity between the Manager nodes and Transport node vmwNsxTDataCenterTransportNodeName (vmwNsxTDataCenterTransportNodeAddress) and no firewalls are blocking traffic between the nodes. On Windows Transport nodes, ensure the nsx-proxy service is running on the Transport node by invoking the command `C:\NSX\nsx-proxy\nsx-proxy.ps1 status` in the Windows PowerShell. If it is not running, restart it by invoking the command `C:\NSX\nsx-proxy\nsx-proxy.ps1 restart`. On all other Transport nodes, ensure the nsx-proxy service is running on the Transport node by invoking the command `/etc/init.d/nsx-proxy status`. If it is not running, restart it by invoking the command `/etc/init.d/nsx-proxy restart`.
