In recent years, it has become very important to protect one’s privacy online. To that end, more and more people are using virtual private networks (VPNs) in order to access the Internet in a secure and anonymous way. These VPNs create secure tunnels from the client (you), through to the server or end point via their network. When using such a tunnel, you can’t be seen online and hackers are unable to access any of the data that you might give to a website, allowing you a stress-free online experience.

Despite their usefulness, there are sometimes issues with VPNs. Even though there are a huge range of VPN options including various functions and price costs, almost all of the VPNs are likely to have an issue at some point. Sometimes, you will find that errors pop up and you are unable to make the connection, which can be frustrating if you want to perform a monetary transaction or another action that requires high levels of security. Whilst these issues may initially be somewhat frustrating or even daunting to the uninitiated, there are ways that you can fix them yourself without having to contact the support staff of your particular VPN.

With that in mind, we will show you what the issues are, how they are caused and of course, demonstrate how you can resolve them from home. But if some of these errors persist, then it may be time to either contact the support staff or consider switching VPNs to a service that offers better internet connectivity.

There are a large number of different error codes that you will find popping up; in fact there are hundreds of potential issues. However, there are a few that are more common than others, and it is these issues that we will focus our discussion on. There are some preemptive measures that you can take when you are setting up the VPN in the first place, such as ensuring the right network settings are in place and that any firewalls you might have are not interfering with the VPN. Often, these are the most common issues with a failing VPN connection.

In this specific article, we will focus on those VPN issues that come from the Cisco VPN. Read on now to find out all you need to know about some of the more common VPN error codes.

Cisco VPN error 56 explained

Unlike some of the other error codes we have mentioned, this one is actually specific to the Cisco VPN client. Cisco VPN error 56 often appears during the installation process of the programme installation during running Windows startup and even shutdown. Sometimes it even pops up during the installation of a Windows operating system. When you get this problem, it is important to actually pay attention to when this error pops up, as it can affect the way we troubleshoot and solve the problem.

There are a few symptoms of Error 56. Often displayed as a Cisco VPN Client Error 56, it will often surface, crashing an active programme. In some cases, your PC may also crash when the Error 56 pops up during the running of the same programme. Usually when it comes into effect, you’ll find that your computer is running a lot slower than usual and may even freeze for short periods at a time.

A number of things can cause the Error 56 message to pop up on your computer. The first of these is usually because of a corrupt download or an installation of the Cisco VPN client software that is incompletely downloaded. It can also be caused by corruption in the registry found on Windows if you have recently downloaded the Cisco VPN, or other client-related software has been installed, or even uninstalled.

Error 56 can also occur if you have a virus or other malware on your computer, and this has corrupted the Windows system and the files held there. Finally, it can be caused by a secondary programme acting in a malicious manner or even by accidentally deleting Cisco related files. Due to the fact that the cause of the Error 56 can be from multiple sources, it is important to troubleshoot each of the potential causes in order to stop it occurring again and again.

How to solve Cisco VPN error 56

The Cisco VPN error 56 occurs in Windows 7, Windows 8, Windows 10, Windows XP and Vista. The following methods should help you to get rid of the problem but as we go through the list, the methods do get harder and more time consuming. We recommend starting from the top if you need to troubleshoot in order to save yourself some time.

First up, you should repair any of the registry entries that are associated with Error 56. This means you will have to manually edit the registry to remove any of the invalid 56 error keys. However, unless you are well versed in this, i.e. a PC professional, we do not recommend taking this route. Because of this, if you are attempting to do it yourself, we suggest you use a registry cleaner software such as WinThruster to make sure that you proceed correctly.

The second step in the process is to do a full malware scan of the PC. There’s a chance it could be connected to malware and these intruders can do a lot more damage if they are not found quickly. The third option is to clean out the system junk, which is essentially all the temporary files and folders found on your computer. During your usage of the computer, files will build up and these can slow down the running of a programme if they are not cleaned out. Additionally, they can conflict with files on the computer or cause the hard drive to become overloaded.

In some cases the error 56 is related to corrupt drivers or those that are out of date. Because of this, it is important to keep all your drivers updated. One day, the drivers can work fine, the next, they can stop for no apparent reason. It can be hard to find the specific driver for the error, even if you are experienced in this area. Because of this, and the time and complex nature of this potential fix, we suggest using a driver update tool that will do the work for you.

It can also help to uninstall and reinstall the Cisco VPN client programme as long as you know that it is the one that is related to the Cisco systems VPN client error 56. You can also run a Windows System file checker, install all the updates that Windows has available or, if the worst comes to the worst, do a full reinstallation of Windows onto your laptop, though this would be the last resort.
