Resetting an Azure Site-to-Site VPN Connection – Lost Connectivity

Occasionally an Azure VPN connection will disconnect and not automatically reconnect again. This could be if the remote device (router or firewall on-premise) loses Internet connectivity or power. To reset the site-to-site VPN connection follow the below steps.

1. Log in to the portal for the customer affected (https://portal.azure.com)

2. Go to the “Virtual network gateways” blade down the left hand side

3. Select the Virtual Network Gateway affected and click Reset, shown in Yellow highlight below

4. You will get a notification to show that the Virtual Network Gateway is being reset

5. You should then get one to show that the Reset was successful, and connectivity should be restored.
