How to Solve Error 812

Once the April 2018 Windows Update was released, a number of users were unhappy when they were confronted with VPN Error 812. While many VPN errors are common, 812 isn't one of them. While the problem may be relatively rare, it isn't difficult to resolve it. The error might just be a case of communication issues between the Net Promoter Score (NPS) and clients. So, if you do come across it, don't worry: it's not the end of the world.

While you can get plenty of advice on fixing VPN issues online, here we're going to zone in on how to fix Error 812 should you encounter it. The error is uncommon, yes, but it's also technical. So, make sure you clear any distractions before you go ahead and follow these instructions.

Unable to Reestablish Connection

When you see the error, you're unable to reestablish a VPN connection in Windows 10 or below, once it's been disconnected. As the error message states, it's related to the RAS/VPN server's policy configuration. Before you start with the following, check that your login credentials (username and password) are correct.

Method 1: Set Up the External DNS

1. Go to the search box in Windows and enter ncpa.cpl

2. Under Network connections, choose the relevant VPN connection, and click on Properties

3. Change the Primary DNS to Domain Controller

4. Access the Secondary DNS to set up the External DNS

5. Modify the Primary DNS range to 8.8.8.8. Save the settings and restart the VPN

Hopefully, the error will disappear. If it's still there, however, you should get in touch with your VPN service provider, as the issue will be coming from the server. There's another thing you can try before doing that, however.

Method 2: Contact your Network Administrator

Another reason that you could be seeing the error is that you lack sufficient access rights. It might simply be that you require administrative access. If this is really the reason, the thing to do here would be to reach out to your network administrator, and request that they update your permissions. You should verify all protocol and network authentication permissions. Also, double-check that you've entered the correct credentials. The issue can sometimes be a result of the incorrect username and password being entered.

Method 3: Contact Your VPN Service Provider

If the previous two methods failed to resolve the issue, don't give up just yet. There's still a way you can still check the latest Forex news and anything else you want to read up on away from the prying eyes of your ISP. The final method we're recommending here is for you to reach out to your VPN service provider.

Your VPN provider will likely understand what's going on and will be able to advise you accordingly. Their technical team will be trained and available to help, and they'll probably be familiar with the issue. Contact them for assistance, so they can tell you exactly what to do.

Wrap Up

There are multiple ways of resolving Error 812. Just try one at a time and check your VPN connection again with each method. If the problem persists, try a different VPN client. Before you do, however, put in some research time by using your favorite search engine and reading some reviews. A decent VPN for Windows 10 client will offer a larger number of worldwide servers and be focused on privacy.
