CoPilot is not reponding

Run the Copilot connectivity troubleshooter first because it checks firewall rules and other connection blockers that may remain relevant after the VPN application has been removed.

1. Check Copilot connectivity

1. Open Start, search for Get Help, and open it.
2. Enter Copilot connectivity troubleshooter in the search box.
3. Start the troubleshooter and apply any recommended fixes.
4. Reopen Copilot and send a new prompt.

The results page will identify detected blockers and suggested remedies.^1^

2. If connectivity passes, repair the Copilot app

Since NordVPN has already been removed, do not reinstall it as part of this test.

1. Open Start > Settings > Apps > Installed apps.
2. Find Copilot.
3. Select the three-dot menu > Advanced options.
4. Select Repair, then test Copilot.
5. If it still does not respond, return to the same page and select Reset.

Resetting can remove the app’s saved data and require you to sign in again. Windows documents Repair first and Reset only if repair does not resolve the problem.^2^

If Advanced options is unavailable, update or reinstall Copilot through Microsoft Store > Library > Get updates.^3^

3. Reset Windows networking only if the problem remains

A removed VPN can leave network-adapter settings behind, but the available information does not establish that this is the cause. Use Network reset only after the preceding checks:

1. Open Settings > Network & internet > Advanced network settings > Network reset.
2. Select Reset now > Yes.
3. Wait for Windows to restart.
4. Reconnect to Wi-Fi or Ethernet, then test Copilot.

Network reset removes installed network adapters and their settings, then reinstalls the adapters with default settings after restart. It can also change known connections to the Public network profile and may require other VPN or virtual-networking software to be configured again.^4^

If Copilot still does not respond after all three stages, note whether it works in a web browser and record any message shown by the app. That distinction—app-only failure versus all Copilot access failing—will determine the next troubleshooting path.
