The infamous Error 807 is one of the most common issues VPN users run into on contemporary Windows machines and its general nature also means there’s no universal fix for it. However, troubleshooting it isn’t that complicated and that’s precisely what this article will walk you through.
The full error text associated with the problem in question is: “Error 807: The network connection between your computer and the VPN server was interrupted. This can be caused by a problem in the VPN transmission and is commonly the result of internet latency or simply that your VPN server has reached capacity. Please try to reconnect to the VPN server. If this problem persists, contact the VPN administrator and analyze quality of network connectivity”.
Note that this exact wording only applies to versions of Windows 10, Windows 7, Windows 8, Windows 8.1, and Windows XP operating systems. Anything else, regardless of how similar it sounds, warrants its own unique course of investigation.
According to Microsoft itself, most instances of Error 807 can be attributed to bad Internet connections, firewalls and antiviruses that are too eager, server overloads (or congestions), and dumpster fires known as local caches – in that order.
With that in mind, here’s how to attempt resolving Error 807, starting with the simplest fixes:
A step-by-step troubleshooting guide
Are you even connected to the Internet and how stable is that connection of yours in the first place? Disable your VPN and make sure you can access websites without it. If your connection seems slow or spotty, run the Windows troubleshooting tool by right-clicking the Internet connection icon in the bottom-right part of the system tray and selecting the first option from the top of the pop-up menu.
Still here? Now’s the time to restart your router manually because your real dynamic IP address may not play nicely with your VPN provider for any number of reasons.
If you’re running any sort of firewall, including those built into antivirus software, disable it and check whether that solves your issue. If it does, you’ll need to whitelist your VPN server before enabling the firewall again, or drop using it entirely.
Are you on a metered connection or roaming? Press the Windows key, then type in VPN and click on the VPN Settings option to see whether your computer allows VPNs in those scenarios (and fiddle with the toggles if it doesn’t).
Yes, the fix can be as simple as hitting these switches while quickly and audibly releasing some air through your nose
In some cases, the Error 807 is simply a result of the wrong syntax being used while configuring a virtual private network. This is hardly a user error and more of a design oversight but nevertheless, you can (attempt to) fix it by navigating to your VPN software settings, finding the server/VPN address section and removing the “http://” part from the field, as well as the final “/” mark. Note that you should manually restart your router after making this change.
While you’re at it, do make sure that the actual VPN server address you’re using is correct, i.e. that it’s the one provided by your VPN service of choice. The same goes for your username and password.
Your VPN Settings/Properties should also display some sort of a PPTP option; that’s short for “VPN to Point to Point Tunneling Protocol” and tends to be the cause of quite a few Error 807 prompts.
Then, clear your local browsing data, including history, cookies, and registry entries. Every modern browser allows you to handle those first two items in just a few clicks but taking one look at your Windows registry will probably not end well for your belief that people who code for a living must know what they’re doing (hint: it’s a mess).
Before going crazy (i.e. contacting support)
Alas, the mighty “have you tried turning it on and off again” question that’s been resolving countless headaches and inducing numerous new ones in the digital era also has to be mentioned alongside the Error 807; in many cases, restarting your computer does, indeed, resolve it thanks to what even seasoned IT professionals describe as magic and fairy dust.
If everything else fails, you’ve little choice but to contact your dedicated VPN support; if you’re paying for your VPN, you should have one available 24/7 and if you aren’t or you don’t, definitely consider changing your provider because a free VPN is hardly worth it.
For issues with Error 807 on company-issued desktops and laptops, you might want to consider contacting your sys admins directly, especially given how you might not even be able to complete all of the aforementioned troubleshooting steps without them, depending on your level of user privilege.
