One of the most common issues seen when working with a Microsoft Windows-based virtual private network is VPN error 619 - "A connection to the remote computer could not be established." With some older VPN servers, the error message says "The port was disconnected." instead.

What Causes VPN Error 619

This issue occurs when the computer is trying to establish a new connection to a VPN server or when it is suddenly disconnected from an active VPN session. The Windows VPN client begins the connection process and then typically pauses at the "Verifying username and password" step for several seconds before the 619 message appears.

Different types of VPN clients may experience this error including those that run using PPTP - Point to Point Tunneling Protocol.

How to Fix VPN Error 619

When you see a VPN error 619, there are several remedies you can try to resolve the connection issues that trigger this error:

  1. If two or more VPN clients are installed on the computer, ensure only one is running to avoid conflicts. Check both for running applications and also for Windows services. Reboot the computer if necessary to ensure all other applications are stopped.
  2. Firewalls and antivirus programs that block access to the VPN ports may be running. Temporarily disable these to troubleshoot.
  3. Try other standard repairs and troubleshooting steps. Reboot the client computer. Delete and reinstall the VPN client configuration settings. Find another computer that has a working setup to compare your network configurations with the properly working computer, looking for any differences.

Intermittent network connectivity issues can cause error 619 to appear one time but then it doesn't reappear when the user restarts the client.

Other Related VPN Error Codes

Other kinds of VPN failures can occur that appear similar to VPN error 619:

  • VPN error 645 - "There was an internal authentication error" occurs on obsolete versions of Windows (including Windows XP) when issues with the username and/or password prevent login. Users most commonly trigger this error by entering an incorrect password on the client, or by having password encryption enabled.
  • VPN error 800 - "Unable to establish the VPN connection." VPN Error 800 indicates the client is unable to reach the target VPN server over the network, but it doesn't give any indication why or when. In contrast, error 619 occurs only after the client reaches the server and attempts to complete the connection process. Users can trigger this error by specifying an invalid VPN server name, for example.
  • VPN error 809 -  "The network connection between your computer and the VPN server could not be established because the remote server is not responding." Clients report VPN error 809 if their attempts to communicate with the server are unsuccessful and exceed the time limit for a Windows VPN connection setup.
