How To Fix VPN 800 Errors

Active internet users who value their privacy should invest in using a VPN. A good VPN service can help you secure your connection and keep all online activity anonymous from shady websites that want to sell your private data to the highest bidder. They may also allow you to bypass certain region-locked websites and services if that’s something that interests you.

As great as a VPN is, they are not foolproof. Sometimes it fails to establish a connection, resulting in the message ‘Connection failed with error 800’. What does this error mean?

If you see this error, it means that the VPN app installed on your Windows PC cannot connect to the VPN service. The reason for all this can be traced back to some of the usual suspects, including VPN app configuration, firewall complications, your internet connection, or VPN server availability.

How To Fix VPN 800 Errors

To fix this error, make sure to follow these methods to re-establish a VPN connection.

Restart the app

Chances are you’ve already tried this step. Most people will already understand the ‘turn it off and on’ approach. All you need to do is restart the VPN app to see if that fixes the problem.

But since you’re going to be following all of the methods listed here in the order they’re written, you’ll want to repeat this step. Instead of just pressing the ‘x’ on the application to close it, you also need to go to the Task Manager to close it.

Right click on the taskbar and select task management† Scroll through the Processes tab looking for a copy of your VPN app. If you find it, right click on it and select End of task to ensure that any process associated with your VPN app is closed.

Restart the app to establish a connection.

Check VPN Settings

If this is your first time using the app, make sure you entered the username and password correctly. They must match the same username and password set for you by the VPN administrator.

Check the VPN app settings, especially the network settings, and make sure they match the settings required by the service. You should be able to find these details on the VPN service provider’s website.

VPN services are configured in different ways from service to service. To make sure the app is set up correctly, contact your VPN provider for the necessary setup information to avoid further complications.

Endpoint server may not be available

Before rebooting, make sure that the endpoint server you selected is still running. Most VPN apps allow you to manually select the endpoint server, while others automatically select the fastest route for your internet speed.

Choose a different endpoint server than the one you currently selected. If you can establish a connection after the change, then the problem is with the other endpoint server.

Restart device

So restarting the app didn’t help, maybe restarting your device will. A full reboot has the power to fix many things related to network and connectivity issues. This is very true for Windows network problems for which they are notorious.

Just restart your device, whether it’s a PC, tablet, or phone, and see if the VPN app can establish a connection.

Internet connection problems

Checking the status of your connection seems like the most logical step at this point. Have you noticed an intermittent connection while surfing the web? Are you using an Ethernet or WiFi connection?

You can start the status check by right-clicking the Windows Start button (located in the lower-left corner of your desktop) and Network connections from the menu.

From here you will want to select either: Ethernet or Wi-Fi in the menu on the left, depending on which one you are using. The rest of the steps of this method will be the same no matter which one you choose, but for consistency I’ll be using Ethernet.

After choosing your connection, in the main window on the right, select Change adapter options

Right click on your connection and select Properties

highlight Internet protocol version 4 and then click the Properties knob. Set both options to obtain addresses automatically and click Okay† Close all remaining windows.

A manually set IP address may conflict with your VPN’s DNS or IP settings. Try to establish a VPN connection again.

Fast firewall check

Temporarily disable your firewall and try the app again. Firewall-related errors usually mean that the firewall configuration may require additional settings specific to the VPN’s port numbers. If your VPN connects, identify the executable file for the VPN app and let it pass freely through your firewall.

If you still see Connection failed with error 800, re-enable the firewall. At this point, the problem may be on the server side. Sometimes the server may crash because too many clients are already connected.

This is unusual, but the restrictions may vary depending on how the server is set up. It would be best if you either wait to use the VPN at a later date or contact the VPN administrator to let them check things on their side.
