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.
How to solve VPN error 800
There are a number of different options that you can utilise in order to get things going again, particularly if the error occurred on a Microsoft Windows based machine. Whether it is Windows XP, Windows 7, Windows 8, Windows 8.1 or Vista, there are ways that you can solve it yourself. 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.
VPN error code 691 explained

Happily though, out of all the VPN errors that pop up VPN connection error 691 is actually one of the easiest to solve and one that is caused by the least offensive problem.
For the most part, the error 691 connecting to VPN message occurs when the connection failed because the username and password combination that was given by you, the client, was not recognised by the server. It could also be that the authentication protocol was not permitted on that particular remote access server. This means that even when using a high-profile VPN such as Pure VPN, error 691 can still occur.
Essentially, the VPN connection error 691 occurs when the authentication part of the connection failed because the incorrect information or credentials was given to the server.

To ensure that the password is correct and that there is no repeat of the error 691 on VPN, we suggest that you ensure that the Caps Lock is not on when you are typing. It’s also important to make sure that the protocol for authentication you’ve selected for the server is actually permitted by that server.
VPN error code 720 explained
When using a VPN it is relatively common for an issue of some sort to pop up during its use. VPN error 720, a connection to the remote computer failed, is one of the most common of these. This is simply the inability of the computer or device to actually reach the server. This is because the IP address is not working properly and means that you’ll need to actually establish a valid server IP address in order to continue surfing the Internet in an anonymous fashion. Even if you’re using Windows VPN error 720 can and will occur if things aren’t quite working right.

VPN error code 807 explained
Error 807 is a common VPN issue where the network connection between the client computer and the VPN server gets interrupted. In fact, this issue is more about the server than the actual device that you are using. Often, this message will pop up on a range of operating systems including a Microsoft VPN error 807 Windows 10, Windows 8.1.
Usually this issue is caused by a problem within the VPN transmitting across to the other server. The result of this is from latency or even that your VPN server is at capacity. It can also be from congestion within the server, a firewall blockage, a faulty Internet connection or even a system cache that has become overloaded. In these instances, you don’t need to panic, as there are things you can do to reconnect and make sure you can surf anonymously online.
For the most part, this simply involves reconnecting to the VPN server but if the problem becomes a continuous one, we would suggest you contact the administrator to see what the quality of the network is actually like.

Step three requires you to check the VPN IP address, password and username to insure that all of them are correct. Finally you will need to check through the VPN Properties section within the Security Tab and make sure that the connection type is set to Point-to-Point Tunneling Protocol also known as PPTP. Selecting the IP address of the VPN and checking the connection should see you back in business.
Another very simple method of fixing this issue is by checking the Internet connection. If the Internet is not working correctly, it is important for you to simply unplug and restart the router. Alternatively you need to unplug the LAN and then replug it.
Once you have completed one or all of these steps, you should find everything functioning smoothly. If this error keeps coming up however, it might be time to contact the support staff of the particular VPN you are using.
