In this article we will show you how to Fix “VPN 800 errors” on Windows 11/10. A Virtual Private Network (VPN) is a way for a local client to connect to a remote computer over the internet in a safe way. You get a VPN error message when you try to join to a VPN but can’t. There are a lot of different error codes, but only a few of them happen often.
VPN error 800 “Can’t set up the VPN connection” is a usual error when working with virtual private networks. This error code doesn’t tell us why the link failed, though. VPN is one of the best ways to keep your online privacy safe, but there are times when it doesn’t work right. You can also go to the official Microsoft support site for more information about this error.
Users of Windows 11/10 have said that they get the message “Connection failed with error 800,” which makes it impossible for them to connect to their VPN. To make a long story short, a VPN, which stands for “Virtual Private Network,” lets a private network safely travel through the Internet’s “jungles,” which are full of malware, hackers, and other dangers.
Ways to Fix “VPN 800 errors” on Windows 11/10
Check Firewall & Router isn’t interfering in your VPN Connection
To see if a client firewall is causing VPN error 800, turn it off briefly and try to connect again. Failures that have to do with the firewall show that the firewall needs to be updated with more settings that are special to the port numbers that the VPN on that network is using. Most of the time, these port codes are TCP port 1723 and IP port 47 for Microsoft Windows.
Let your VPN and PPTP use the router. Also, if you have never linked to the server with the local router you are using, the router may need a firmware update to work with the VPN.
Check the connection between the client and the VPN server
You will have to ping the server and wait for an answer to see if there are any network problems caused by a bad connection between the client and the VPN server. So as to:
- Press ‘Windows Key + X’ and select ‘Command Prompt (Admin)’
- Once ‘Command Prompt’ opens, enter ‘Ping’ followed by the address you want to ping. Example ‘ping myvpnaddress.com’.
- Now press ‘Enter.’
You should keep track of how long the server takes to reply. When a network goes down randomly, sometimes it helps to wait a minute or two and then try to join again. Trying to join from a different client device can also help you figure out if the problem is specific to one client or if it’s a common one.
Check the username, password, and server type
- Click ‘Win + I’, select ‘Network & Internet’
- Click on ‘VPN’ appearing in the right-side panel. This right pane displays all the Virtual Private Network options.
- Click on your ‘VPN service’ and go to ‘Advanced Option’. This will open a pop-up that allows you to edit your VPN details.
- Check if IP address, username, and password are correct. Modify if you find any discrepancies and try once again. Ensure the server name or address doesn’t include “http: //” and “/”. If either of the symbols is placed in the 3rd box, it will show this error.
- If this doesn’t work, change your ‘VPN type’ to ‘Point to Point Tunneling Protocol (PPTP)’.
