How to Resolve Error 800 “Unable to Establish VPN Connection”
We will help you understand how to easily fix VPN error 800 to successfully establish a VPN connection with the server you want. All you are required to do is to use the following tips:
1- Make sure that the connection between the client device and the local network is working properly. You can check that by pinging the server. Put in mind that there are some VPN servers are set up in a way to discard ICMP requests, but you can give it a try.
2- Ensure that your firewall is not blocking all access from VPN connections. You can check if your firewall is blocking your VPN connection by temporarily disabling it, and then try connecting to your VPN server once more. If your firewall indeed interferes with your VPN connection, this probably means that it needs to be updated to include certain VPN port numbers, for example, TCP port 1723 and IP port 47 for Windows-based VPN service providers.
3- Make sure to specify correct server name and address for your VPN connection. When you enter your details, such as: name and IP address, you must make sure that these details match the ones configured by your VPN administrator. Usually, users make mistakes when writing the address, therefore, be sure of what you specify before establishing a VPN connection. On the other hand, sometimes VPN service provider make changes to their IP addresses.
