How to fix VPN error 811

Windows VPN 811 error solution:The network connection between your computer and the VPN server could not be established because the remote server is not responding. This is typically caused by a pre-shared key problem between the client and server. A pre-shared key is used to guarantee you are who you say you are in an IP Security (IPSec) communication cycle. Please get the assistance of your administrator to determine where the pre-shared key problem is originating.

 

 

What is a VPN?

VPN’s (Virtual Private Network’s) were first used by companies to enable their employees to securely access internal systems such as email remotely (e.g. from home or while on business trips). Today they are increasingly being used for personal use by individuals to protect their privacy while online in public places (e.g. when using the wi-fi connection in a cafe) or in a country where the internet is censored / blocked (e.g. China, Saudi Arabia…).

Why do I need a VPN?

Whether you’re an expat living in a foreign country where the internet is heavily regulated, a mobile user constantly on the road, or just someone concerned with maintaining their privacy online, having a VPN is becoming essential.
