Firewall tools are always useful because they prevent potentially dangerous applications from accessing the Internet. Unfortunately, sometimes these tools can interfere with the clock and cause this error.

To fix this error, temporarily disable the firewall and see if that fixes the problem. If the problem persists, you should remove your firewall completely.

Users have reported that after setting the firewall to default mode or disabling it completely, they were able to sync their clocks without any problems.

In addition, you must configure your firewall to allow NPT to access UDP port 123. If you have changed your router’s firewall configuration, you may also need to enable UDP port 123 on your router.

Do you need to configure your router? With this software you can easily change all settings.

Check if the firewall is blocking a port or an application by following the few steps in this guide.
