What Causes VPN Error 789?

There are several potential causes for VPN Error 789, which can sometimes make it tricky to diagnose and fix. Here are the most common culprits:

  • VPN Protocol Issues
  • Problems with Network Connections
  • Antivirus and Firewall Conflicts
  • Outdated VPN Apps
  • VPN Server Issues
  • Software Bugs and Glitches
  • System Configuration Problems

VPN Protocol Issues

VPN protocols like OpenVPN, IKEv2, L2TP, and SSTP are used to establish the encrypted tunnel. Issues with protocol handshakes and configuration can lead to Error 789.

For example, an outdated VPN protocol version, a firewall blocking the protocol, or incorrect protocol settings can prevent the tunnel from being created properly.

Problems with Network Connections

Any network issues that interrupt or affect connectivity between your device and the VPN server can cause VPN Error 789.

This includes problems like unstable WiFi, faulty ethernet, ISP throttling, changing between networks, loss of internet access, and using restrictive public/corporate networks.

Antivirus and Firewall Conflicts

Overly restrictive firewalls and antivirus programs may interpret VPN connections as suspicious. If they block access to VPN protocols and processes, it will lead to Error 789.

You’ll need to configure them to allow and trust your VPN app. Certain antivirus programs, such as Norton and McAfee, are known to cause issues.

Outdated VPN Apps

Using an outdated VPN app that isn’t compatible with your device’s OS or isn’t configured properly can also trigger Error 789.

Keeping your VPN app updated is important to avoid conflicts. Check the App Store or Play Store for the latest versions.

VPN Server Issues

Problems with individual VPN servers you connect to can also interrupt the tunnel and cause Error 789. Server outages, congestion, remote config changes, instability, and distance/latency can be factors.

Software Bugs and Glitches

Some instances of VPN Error 789 may be due to simple software bugs and glitches. Like any app, VPN services can have code issues that lead to errors like 789 occasionally.

Reinstalling the VPN app often fixes these types of intermittent glitches.

System Configuration Problems

Misconfigured system settings, date/time issues, DNS problems, OS version conflicts, etc., can sometimes interfere with VPN connections and cause Error 789.

Updating your system and checking settings can help avoid these types of conflicts.

How to Fix VPN Error 789: 7 Easy Ways

If you encounter VPN Error 789, there are a number of troubleshooting steps you can take to try and resolve it:

  • Restart Your Device and Reconnect
  • Try Different VPN Protocols
  • Change VPN Servers
  • Update the VPN App and OS Software
  • Reinstall the VPN App
  • Check Antivirus and Firewall Settings

Restart Your Device and Reconnect

As simple as it sounds, restarting your device and reconnecting to the VPN is a good first step. This will refresh all connections and often clear up any minor software glitches causing Error 789.

Try Different VPN Protocols

Change VPN Servers

Connecting to another VPN server location can help determine if the issue is related to an individual server you’re using rather than the overall service.

Update the VPN App and OS Software

Download the latest versions of your VPN app and operating system in case the error is due to a compatibility bug. Keeping software updated prevents many issues.

Reinstall the VPN App

If all else fails, completely uninstalling and reinstalling the VPN app can clear up underlying software conflicts that may be causing Error 789.

Check Antivirus and Firewall Settings

Add exceptions and allow permissions for your VPN app in your antivirus and firewall. Also, disable them temporarily to see if it fixes Error 789.

Contact VPN Customer Support

Explain the error to your VPN’s customer support. They may have additional troubleshooting tips or determine server issues on their end causing the problem.

Following these seven steps will help resolve most occurrences of VPN Error 789. We’ll now look at how to fix it for individual VPN services.

How to Prevent VPN Error 789

To help avoid VPN Error 789 occurring in the first place:
