1. Fixing VPN Error 800
1.1 Method 1: Restarting the VPN Application
To fix VPN Error 800 in the VPN application, the first solution is to try restarting the application. Close the VPN on your Windows computer, then right-click on the Taskbar and select Task Manager.
Try selecting a different endpoint server and reconnect to see if the VPN 800 error persists. If the error disappears, the cause of the issue lies with the endpoint server. If not, and the error persists, you can explore some other troubleshooting methods in the following section below.
1.4 Method 4: Restart Your Device
If restarting the VPN application does not resolve the error, try restarting your device (such as your computer, tablet, etc.) to see if the 800 error persists. Additionally, traditional device restart solutions may help resolve most other issues and errors.
Restart your device and try the VPN application again to see if the 800 connection error persists.
1.5 Method 5: Check Internet Connection
Sometimes, the cause of the VPN 800 error can be an unstable Internet connection. If you are using Wifi or wired connection, try checking the stability of the Wifi or wired connection.
Follow the steps below:
Step 1: Right-click on the Start button, select Network Connections.
Step 2: Select Ethernet from the menu on the left panel, then choose Change Adapter Options on the right panel.
Step 3: Find and right-click on your Ethernet wired network connection, select Properties.
Step 4: Select Internet Protocol Version 4 and check the box next to Properties.
Step 5: Set the 2 options in the popup window to Automatic and then click OK.
Step 6: Close all windows and confirm the changes if prompted.
Please recheck your VPN connection and see if error 800 persists. If manually configuring IP addresses, it may conflict with DNS or IP settings. Allow your Windows computer or router to control IP addresses and DNS server addresses for VPN to reconnect smoothly.
1.6 Method 6: Check Firewall
Most Firewalls allow VPN traffic without encountering any errors or issues. However, if all the above solutions have been unsuccessful, try disabling your firewall for a few seconds and then attempt to reconnect to the VPN application to see if error 800 persists.
If the error 'Connection failed with error 800' still appears on the screen, try reactivating the firewall. The next step is to identify VPN executable files and allow them through the firewall. Then try reconnecting to VPN 800 to see if the error persists.
