How to fix VPN error 619

One of the most common problems commonly encountered when working with a virtual private network on a Windows platform is a VPN error 619 - "A connection to the remote computer could not be established". For some old VPN servers, an error message will display "The port was disconnected" instead.

The cause of VPN error 619

This problem occurs when the computer is trying to establish a new connection with the VPN server or when the computer is suddenly disconnected from the active VPN session. The Windows VPN client starts the connection process and then usually pauses in the "Verifying username and password" step for a few seconds before the error message VPN error 619 appears.

Different types of VPN clients may encounter this error, including PPTP-based applications - Tunnel point to point protocol.

How to fix VPN 619 error

When you see the VPN 619 error, there are some remedies you can try as follows:

1. If two or more VPN clients are installed on the computer, make sure only one client is running to avoid conflicts. Test both to run Windows applications and services. Restart the computer if necessary to ensure all other applications have been stopped.
2. Firewalls and antivirus programs block access to VPN gateways that may be active. Temporarily disable them to fix the problem.
3. Try other standard troubleshooting steps. Restart the client computer. Delete and reset the client's VPN configuration settings. Find another computer that has an active setting to compare your network configuration, then find out any differences between the two. That may be the cause of the incident.
4. The intermittent network connection problem can sometimes cause the 619 error to appear but then it does not appear again when the user restarts the computer.
