“Connection Error: Secure VPN has experienced a connection failure. Please try again later.” Before moving on to fix the Norton VPN, check if your internet connection is working. If you are using a home server, check if the expired certificates of the server are not causing the issue. Also, it will be a good idea to make sure if the Norton Services are up and working. Moreover, make sure to update the Windows & Norton VPN to the latest builds. Last but not least, check if changing the region (or setting it to Automatic) in the VPN settings solves the connection problem.
Solution 1: Delete the Temp Files and Old Norton Installers

Moreover, check if installing the Surf Easy VPN (as it is part of the Norton Lifelock) & then repeating the above solution resolves the issue.
Solution 4: Reinstall the WAN Drivers/Adapters
The Norton VPN might fail to connect if the WAN network drivers are corrupt. In this scenario, reinstalling the WAN drivers/adapters may solve the problem. If the issue persists, then enable Show Hidden Devices in the Device Manager and retry the above solution.
Solution 5: Disable the Fast Startup of Your System
The Fast Startup feature is quite useful as it tremendously decreases the boot time of your system. But during this process, an essential source for the operation of the Norton VPN may get into an error state & thus cause the issue at hand. In this context, disabling the Fast Startup of your system may solve the problem.

Norton VPN might not work if an application or its service (especially, other VPN clients) is hindering the operation of the Norton VPN. In this case, removing/disabling the conflicting applications (or services) may solve the problem. Cisco Any Connect is reported by some users to create the issue, so, disabling its service or reinstalling it may solve the problem.

In this case, editing the settings of your router may solve the problem. But keep in mind that some of these settings may not be available to all users or may be available with some other name.
