Network topology change detected


All of a sudden, I lost VPN connection. I am unable to connect to any of the servers or even disconnect as a matter of fact (it just says “connecting” with the large X - cancel button having no effect). I tried to quit/restart several times but that had no effect at all.

My internet connection is working. I am using a Windows 10 computer with the latest VyprVPN software.

The application log says: Network topology change detected.

Any help would be appreciated.

hey @Z_Fuki,

Sorry to hear you are having connection issues. I can confirm we are not having any server side issues that would cause this to happen. If the application becomes unresponsive in its “connecting” state, then you can use the following steps to restart the service:

  1. Press the Windows key + R
  2. The “Run” box will appear. Type in “services.msc” (no quotes) and click OK.
  3. Find “VyprVPN” in the services list and right-click it.
  4. Click “Stop” to stop the service.
  5. Open Task Manager and end the VyprVPN.exe process if it is still present
  6. Switch back to the VyprVPN service window and click “start” to initiate the service again.

Wait for the service to enable (few seconds), then try opening the application and attempt to connect again. If the application gets stuck in that “connecting…” state again, then please contact our support team directly:

Technical Support

The network topology can happen in a network due to different reasons like a link failure, a Switch (Bridge) failure, or a port transitioning to forwarding state. When a Switch discovers topology change, it generates a TCN or Topology Change Notification.
