Ways to Fix VPN Error 628: Connection Was Terminated By Remote Computer

Before we begin with how to facilitate the resolution of VPN error 628 on your Windows PC, basic errors must be taken care of. You see while using a VPN, there are several mistakes that a user may make unknowingly. Look at the basic things to take care of to ensure that the connection was terminated by a remote computer error that appeared out of a mere fault. 

  • Double-check your VPN credentials
  • Ensure you have a stable internet connection
  • Try restarting your router to check if it is a glitch
  • Disconnect and reconnect your VPN client 
  • Check for updates for the VPN client in use. 

After these basic yet crucial checks, try the following methods if the issue persists. 

Fix 1 – Allow VPN Through Firewall

Windows 11 firewall is quite powerful when it comes to limiting the usage of third-party software on your computer. While the idea is to keep you protected from malicious software, it often becomes an inconvenience as users cannot use their desired applications easily. 

The good thing is that the firewall can be manually overridden, and the VPN client can be allowed through the firewall. This will help you fix the VPN error 628, provided the firewall is the main cause. Here are the steps that will help you out – 

Step 1 – Press Win+R to bring up the Run search.
Step 2 – Use the command firewall.cpl and hit enter to open Firewall settings.

After you have selected the VPN and added it to the list, save the changes and exit. Now open your VPN client and try connecting to a random server. Only now, you may not get the connection terminated by the remote computer error 628. 

Fix 2 – Update Network Protocol Settings

You must allow all the necessary protocols to support seamless VPN connectivity on your PC. Needless to say, with these protocols enabled, your VPN might be able to establish a stable connection. If you already use the IPv4 protocol, try enabling IPv6 to check if it helps.

To ensure that these protocols are enabled or to enable them manually, here are the steps you can follow – 

Step 1 – Press Win+R and use the control command to open the Control Panel.

Step 2 – In the Control Panel, click on Network and Sharing Center.

Fix 3 – Update Network Adapter Drivers

In case the network keeps disconnecting after a VPN due to remote computer error 628, chances are that the issue lies in the drivers that your PC is using. Now, there are multiple drivers involved in the process. For instance, you have your Network Adapter Driver, the WAN miniport drivers, and the VPN connection tunnel driver. 

All of these must work in sync and be up to date to make the most of your VPN connection. If you plan to update these drivers manually, it will take a lot of time, considering each will update one after another. We recommend an automated driver updater tool that gets the job done instantly. The automated algorithm of these tools runs a scan, compares existing drivers with the latest versions available, and installs the updates in just 3 steps – 

Step 1 – Download and Install the application on your PC.

Step 2 – From the home screen, initiate the process using the Start Scan Now.
