How Can I Fix VPN Error 619?

What is "error 619" or "The port was disconnected" error?

Error 619 may pop up on your computer screen when the system is trying to connect to the VPN and the VPN is unable to authenticate the connection. This happens because the Routing and Remote Access Server (RRAS) doesn’t authenticate the domain accounts and the best way to get it working is by re-starting the system.

Operating Systems affected are:

  • Win XP Home and Professional.

Errors appearing on the screen

“Error 619, "The port was disconnected.”

“Error 645, "Dial-Up Networking could not complete the connection to the server”

“Error 930, "The authentication server did not respond to authentication requests in a timely fashion.”

What should I do to solve the Error 619 problem?

There are numerous reasons for a VPN connection to give this error. Some of them are listed below:

  • Remote Computer might be busy.
  • Modem Problems
  • Firewall Issues
  • Hardware Problems

Let’s see how to deal with each of these –

Remote Computer Busy – It sometimes happens that the server you are trying to connect to using the VPN might be busy. A simple solution to this problem is to try to reconnect after waiting awhile. If reconnecting doesn’t solve the problem, then re-starting the system might help.

Modem Problems – At times, your modem may fail to connect the first time and tries to redial the connection. If it starts redialing before it disconnects and you try to launch the VPN connection, error 619 may generate. In this case, it is better to connect after some time or restart the modem and try again.

The modem sometimes might not work efficiently to establish a successful VPN connection.  This can either be because of incorrect setup or a problem with the modem. If the modem is not setup correctly you can follow the steps below:

  1. Click Start.
  2. Go to Settings and then click Control Panel.
  3. Click Connections.
  4. Remove all the connections listed below Dial-up and Virtual Private Networking.
  5. Click OK and then minimize the Control Panel window.

    Once the connections are removed, you can uninstall the Modem completely from the system. But be sure to keep your modem CD handy as you will have to reinstall it later.

    Maximize the Control Panel.

  6. Click Phone and Modem options.
  7. Highlight the Modem and click Remove.
  8. Click OK and Restart the System.

After you do this, insert the Modem CD provided by the manufacturer in the CD-ROM drive and reinstall the drivers. Once the modem drivers are installed, you can configure the settings as per your Internet Service Provider. This should take care of the problem. If not, proceed to the next step.

Firewall Issues – Devices that are used to connect to a VPN, like a router, switch or LAN card might be bound by a software or hardware firewall. If the firewall is not configured correctly it will not let the user connect to the VPN and mark the session as unauthorized. So, configuring the firewall properly can solve the 619 issue.

Hardware Issues – There are a lot of hardware equipment like network cards or routers that can stop working and result in a VPN error. Checking all the hardware equipment for any failures will help solve the problem.
