How to Troubleshoot Common VPN Issues

Like any technology, VPNs can have issues. Connection problems, slow speeds and error messages are just a few of the common issues VPN users face. In this article, we’ll explore some of the most common VPN issues and provide solutions to help troubleshoot and resolve them.

VPN Connection Problems

The most common VPN issue is a connection problem. If your VPN connection is not establishing, you won’t be able to access any online resources. Here are some solutions to fix this problem:

  • Check your internet connection: Make sure you have a stable and reliable internet connection. Try disconnecting and reconnecting your Wi-Fi or Ethernet cable.
  • Restart your VPN software: Close the VPN software completely and restart it. This can help refresh the connection.
  • Check your firewall settings: Your firewall may be blocking the VPN connection. Check your firewall settings and make sure the VPN software is allowed to connect.
  • Try a different server location: Sometimes, the server location you are trying to connect to may be experiencing issues. Try connecting to a different server location and see if that fixes the issue.

Slow VPN Speeds

Slow VPN speeds can be frustrating, especially if you’re trying to stream content or download large files. Here are some solutions to help improve VPN speed:

  • Try a different server location: The server location you are connecting to may be too far away, resulting in slower speeds. Try connecting to a server location closer to your physical location.
  • Check your internet connection: Slow speeds could be due to a weak internet connection. Check your connection speed using an online speed test tool.
  • Change your VPN protocol: Different VPN protocols have different speeds. Try switching to a different protocol and see if that improves the speed.
  • Close other applications: Running multiple applications simultaneously can slow down your VPN speed. Close any unnecessary applications to free up bandwidth.

VPN Error Messages

Error messages can be frustrating and confusing, but they can usually be resolved with a few simple steps. Here are some common error messages and their solutions:

  • Error 619: This error usually occurs when the VPN software is unable to establish a connection with the VPN server. Try connecting to a different server location or restarting your VPN software.
  • Error 800: This error is usually caused by a firewall blocking the VPN connection. Check your firewall settings and make sure the VPN software is allowed to connect.
  • Error 807: This error occurs when the VPN connection cannot be established. Try connecting to a different server location or changing your VPN protocol.

A DNS leak occurs when your VPN fails to hide your IP address and allows your internet service provider (ISP) to see your online activity. Here’s how to fix this issue:

  • Check for DNS leaks: Use an online DNS leak test tool to check for any DNS leaks. (We suggest using VPN Checker)
  • Disable IPv6: Some VPN software does not support IPv6, which can cause DNS leaks. Disable IPv6 in your network settings to prevent leaks.
  • Change your VPN software: If your current VPN software is not protecting against DNS leaks, consider switching to a different VPN provider.

  • Contact your VPN provider: If you’re still having authentication issues, contact
