Key notes
If you experience the Azure VPN gateway not connected problem, this article will help you with some helpful steps to troubleshoot the actual issue.
Azure VPN gateway is required to establish a VPN connection with Azure. This is a very secure gateway that uses various protocols, IPsec, and IKE to secure your connection.
However, sometimes, while establishing a VPN connection, you may notice that the gateway is failing or it has been disconnected and is failing to reconnect.
Even if you have configured VPN correctly on Windows, the issue may repeatedly come on your end if something is wrong internally or on the server side.

1. Enable IKEv2 support on Windows
1.1 Update Windows
If you do not wish to update in this way, you can download the following updates for these specific versions of Windows.

4. Use different client
There are two types of Azure VPN Clients for Windows. One is available as an app in the Microsoft Store, and another one is like an addon that enables Azure VPN as a VPN provider in the built-in Windows VPN settings.
If you are using either of them, try another one to see if it fixes the Azure VPN gateway not connected error. For this, go to theAzure VPN client download page.
5. Configure the VPN device properly
A misconfiguration on the VPN device may be the reason you have been experiencing the problem. In this case, you should check if all configurations are OK.
Microsoft has obvious instructions for configuration on specific devices. You should check them out from thisdevice configuration guide page.
6. Use proper IPsec parameters
Using incorrect IPsec parameters in the configuration can also be why you see the error Azure VPN gateway not connected.
You can check out the supported IPsec parameters by Azure fromthis documentation page. Verify if you are using the correct parameters. If not, correct where it is necessary.
Azure VPN connected but cannot ping
Some users report that even though they are able to secure an Azure VPN connection, it won’t ping.
If this happens to you, it’s possible that your firewall on antivirus is interfering.
Check your settings and make sure Azure is allowed through the firewall.
Other users around the web also recommend confirming that your on-premise devices and your VPN use the same tunnel.
