VPNs are a great way to stay anonymous and protected when surfing the web. To do this, a VPN creates secure tunnels from the client through to the server, all via the Internet. There are many different VPN providers that you can use that offer varying different functionalities and with different costs. However, almost all of them will at one time or another, experience an issue. When an error does pop up, it is important not to be daunted by it as for the most part, you’ll be able to fix these yourself by following the simple processes that we will outline next to each error.

We do understand that these VPN systems can be hard to setup simply because of the technology that is involved. That’s why it can be particularly disheartening to discover an issue or to be faced with an error code. Never fear though, we’re right here to help you through it all.

Usually, when a VPN fails, the client programme will end up reporting an error message, most of the time with an error message in the form of a code. There are literally hundreds of different VPN error code messages in existence, but there are a number that will turn up on a regular basis, and it is these that we will cover in this article.

For the most part, these VPN errors just need a standard troubleshooting procedure in order to ensure that everything is working smoothly once again. Often, these resolutions require something as simple as ensuring that the computer is using the VPN client whilst being attached to the Internet. It can also be important to check that the VPN has the right network settings in place so that it is actually able to work with the VPN server. If these fail, the age-old option of turning things off and on, tends to work miracles. Simply switching off the network’s firewall can help you to figure out what is causing the interference in the VPN. However, some VPNs need even further troubleshooting options if they are to go back to working successfully.

Some of you might have spent the time setting the VPN up and not actually know what to do if there is an issue. The above resolutions are just the basics, so in the rest of the article we will endeavour to cover a number of specific errors, giving you the ways in which to identify any issues.

VPN error code 800 explained

Error connecting to VPN, connection error 800 is the most common issue to occur when you are dealing with a VPN. This error code simply means that a new remote connection was unable to be made and is often listed as “VPN connection failed with error 800”. This usually means that the VPN server is actually unable to be reached, which will be why the messages sent by the client (you) are not reaching the server.

There are many reasons as to why these messages are failing to be sent to the server and normally this has to do with the VPN having an invalid name, or even address of the required VPN server. In other instances there are network firewalls that actually block VPNs from accessing them in this manner, which also results in the VPN tunnel failed error 800 messages.

Another reason for you to have the error 800 VPN tunnel failed code pop up is if the client (i.e. you), have lost your service during the connection time to the local network. The last reason for the error 800 unable to connect to VPN pop up messages is if the IPSec negotiation to the L2TP/IPSec tunnel that the client is using has a poor configuration within its security protocols.

There is a main cause for this, which is often the case when the VPN tunnel is set as an automatic one. This means that with the error 800 the remote connection was not made because the attempted VPN tunnels failed, hence the issue.

The first step is to crosscheck with the username, password and address of the VPN server are all correct. After that, it is a simple thing to ensure that the settings for both the router and firewall will allow PPTP or VPNs to actually go through the TCP Port 1723. In this case, the GRE Protocol 47 also needs to be established in order to allow this PPTP VPN connection.

Windows users who get the Windows VPN error 800 can find all this in the VPN properties. Clicking on the security tab will allow you to change the VPN type to Point to Point Tunneling Protocol (PPTP) thus giving you access once again.
