[Solved] VPN Throws an Error 807 Tantrum Out of the different VPN errors that tend to plague offices, the VPN Error 807 can appear to be among the most straightforward, yet also give users a surprisingly difficult time. It tells you that a connection between two machines is being interrupted, whether due to mismatched VPN clients, an overloaded network or a clogged connection. Do not mistake it with VPN Error 789 which is a different ball play. The full error text 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”.

As much faith as you have in your VPN client, it could very well be the true culprit behind Error 807. For one, a lot of VPN clients use free plans with a limited bandwidth. While this is great for some uses, exceeding the bandwidth can either revert the connection speed back to dial-up times or halt it altogether. We use Ivacy VPN pro in our office, and so long as everyone’s machine is updated to the latest version, everything works smoothly. Regardless of the VPN you’re using, you should make sure that every machine is running the pro version. Likewise, all machines should be using the same version of the software, as just missing an update or two could lead to problems. Fix #2: Reset the machines and see if Error 807 goes away The simplest solutions often work best, and the same is true here. A combination of modem, router and computer reset will oftentimes fix Error 807. Start by turning off your modem and/or router and then unplugging both devices from the computer and whichever power source it has. Wait 30 seconds, then plug both of them back in and turn the devices on (or the device, if it’s a two-in-one router and modem). Still getting the error? We’re guessing you’ve already tried turning the VPN itself off and on (if not, be sure to do that first), so try restarting the computer. If nothing’s changed, type “cmd” without the quote marks in the prompt you get after opening Run from the Windows start menu, then type “netsh winsock reset” in the command prompt, again without the quotation marks. This will issue a command to reset the network adapter, and after it’s finished, restart the computer and see if Error 807 is still popping up. Fix #3: Ensure that the firewall isn’t blocking the connection As useful as they are from preventing all sorts of malicious attacks, firewalls can oftentimes get in the way and cause just as much trouble as they are helpful. If you suspect that your firewall could be the cause of the Error 807, it should be fairly easy to find out whether this is the case. Start by figuring out which firewall your machine is using. Oftentimes, a third-party firewall is going to be installed on top of a working Windows Firewall without the latter being properly configured. For starters, navigate to the Windows Firewall and ensure that it has both an inbound and an outbound security exception for your VPN, then do the same with any third-party firewall you might be using. For a more aggressive solution, you can try temporarily disabling Windows Firewall and the third-party firewall altogether, as well as uninstalling the third-party firewall. While it might seem risky, it won’t really expose your machine that much since you weren’t getting a connection in the first place, and you’ll have a definite answer as to whether security software is causing Error 807. Fix #4: Run a DISM scan and clean your registry and other forms of history Usually, when you start getting into the more technical solutions, you know you’re running out of options. The same is true here, but don’t fret just yet. Your Windows machine will have a built-in DISM (Deployment Image Servicing and Management) utility software, and running it will ensure that something hasn’t gone awry during a Windows update or something along those lines. Still getting VPN Error 807? As a last resort, see what happens when you download a registry cleaner (a lot of people like Ccleaner, though you can use anything similar) and run a full clean, emptying both the registry and a lot of other residual data that might have stuck around. If you’ve tried this and are still getting the error, you’ll know it’s time to haul technical support over so they can take it from here.
