Error 809: The network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because one of the network devices (e.g., firewalls, NAT, Router etc.) between your computer and the remote server is not configured to allow VPN connections.

This error occurs when your system is unable to reach the VPN service. This is usually due to an issue with configuration on your local PC, LAN or an issue in the communication between your system and our VPN server.

Please check the following:

  1. Any Anti Virus software whitelists FlowVPN
  2. Ensure no other VPN applications are enabled
  3. Check your route configuration and ensure the “IPSec Passthrough” is enabled
  4. Change VPN Protocol
  5. Change VPN location
  6. Whitelist FlowVPN in your firewall


VPN Error Code: 868

This error occurs when the domain name for our server cannot be looked up. Please try changing to a different VPN location, or configure the connection manually and use the IP address for the VPN server.
