You should use a virtual private network (VPN) if you want the best possible results for protecting your online privacy and accessing prohibited content. However, it is quite aggravating when you are unable to correctly set it up or when the connection cannot be made, which results in a variety of error messages.
The most typical reason for this is that the user entered their credentials incorrectly; however, the VPN connection could potentially be down due to issues with the server or the internet. Incompatibility with IPv6 may also be to blame for this issue, as might malfunctioning Remote services or network protocols, tainted WAN Miniport drivers, and ports that have been closed off. VPN Not Working on Windows How to Fix
There is a possibility that there is an issue with the internet. First, you should either switch to a different VPN server or unplug the virtual private network to see if the standard connection is still operational.
Check to see that you are logging in with the appropriate credentials. Verify further that the password has not been altered by the provider of your VPN service.
Check the date and time on your computer to be sure they are correct.
Make sure that your copy of Windows is running the most recent update.
In the event that you are utilizing a third-party VPN application, you should attempt to update or reinstall it.

The Virtual Private Network (VPN) is one of the alternative connection ways that WAN Miniport device drivers make available. In the event that it is out of the current or corrupted, your virtual private network (VPN) may become inoperable or display a variety of problems.
To resolve this issue, you can either update them (if that is even an option) or just reinstall them by following the methods that are provided below:
It is vital that the relevant ports stay open in order to create a connection to a virtual private network (VPN), which makes use of a tunneling protocol.
The following chart should be of assistance to you in determining which TCP and UDP ports your firewall should not block:
If your virtual private network software uses User Datagram Protocol (UDP) instead of TCP, you should be aware that this protocol is meant to establish connections that can tolerate loss and have low latency. In the event that there are issues with the network’s security, your VPN connection may become inoperable. If this is the case, you can create a UDP exception by using the Windows Registry Editor to add the DWORD named “AssumeUDPEncapsulationContextOnSendRule.” This will allow you to send UDP packets.
