Windows – VPN Connection shows error 720 in Windows 10

ethernetnetworkingvpnwindows 10

I'm working in a company with a local network and Internet is shared using VPN connections. I'm connecting to the network with my laptop.

Yesterday I did a Network Reset and after that I cannot connect to the VPN Server and The network support couldn't find the solution.
I did another Network reset, disabled Comodo Firewall and the problem still exists.

This is the error:

Can't connect to {Connection Name} A connection to the remote computer
could not be established. You might need to change the network
settings for this connection

Other Info:

  • All computers are connecting to the network using Ethernet connections
  • This connection is working perfectly on other computers.
  • My LAN setting is set to DHCP and all other settings are as default
  • I can access other network resources like shared folders
  • I found out that user authentication is getting done successfully. Because when I try to connect with wrong credentials, user validation error occurs.
  • I could not find anything related in Windows Log Viewer

These are my connection properties:
