VPN Error Code: 809




Error Description: 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, routers, etc) between your computer and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device may be causing the problem.

Possible Cause: This error usually comes when some firewall between client and server is blocking the ports used by VPN tunnel

a> PPTP port (TCP port 1723) is blocked by a firewall/router. [Applicable to tunnel type = PPTP]

b> L2TP or IKEv2 port (UDP port 500, UDP port 4500) is blocked by a firewall/router. [Applicable to tunnel type = L2TP or IKEv2]

Possible Solution: Enable the port (as mentioned above) on firewall/router. If that is not possible, deploy SSTP or OpenVPN based VPN tunnel on client – that allows VPN connection across firewalls, web proxies and NAT.
