Why isn't VPN Secure Connection connecting?

The VPN Secure Connection feature in Avast One may not connect if you already have another VPN app installed and connected on your device, such as Avast SecureLine VPN. If you are connected to another VPN, it is likely that VPN Secure Connection won't work properly. To ensure your VPN Secure Connection remains uninterrupted, disconnect other VPN services that may be running on your device.

If VPN Secure Connection is still unable to establish or maintain a connection, try the following troubleshooting tips:

• Check that your internet connection works when VPN Secure Connection is disconnected. If your internet connection isn't working, check your network configuration.
• If you have a paid version of Avast One, select a different server location.
• Try to uninstall and reinstall the app. For detailed instructions, refer to the following articles:
