How do I fix VPN error 720 on Windows 10?

1. Check if your username and password are correct

    • Go to Network Connections by right-clicking the Start button.
    • Choose VPN.
    • Click Advanced Options after selecting your VPN connection.
    • Select Edit.
    • Check the server’s address as well.
    • When you’re finished, click Save.

Look for open ports in the Windows 10 firewall.

2. Check the Windows 10 firewall for opened ports

    • Press the Start button, type firewall, select Firewall & network protection.
    • Select Advanced settings and Yes (User Account Control) if UAC prompts you.
    • Check the state of the Remote Port under Outbound Rules* (depending on your desired VPN protocol):
      • PPTP – port 1723 over TCP and port 47 over GRE**.
      • L2TP/IPsec – port 1701 over UDP (L2TP***) and ports 500 and 4500 over UDP (IPsec).
      • SSTP – port 443 over TCP.
      • IKEv2 – ports 500 and 4500 over UDP.

The client PC (the one attempting to connect to the VPN server) must have the Outbound Rules defined. If you’re using a VPN to connect to another PC, check the Inbound Rules > Local Port status on the server PC (the one you’re trying to connect to).

**Routing and Remote Access (PPTP-Out) and Routing and Remote Access (GRE-Out) are the default rules.

***Routing and Remote Access is the default rule (L2TP-Out).

If your preferred VPN protocol’s ports are closed, you’ll need to open the firewall ports linked with your VPN protocol.

    • The Network Adapters menu will be expanded.

    • Glue the lines together (press Enter between each line)
      • ipconfig /flushdns
        ipconfig /registerdns
        ipconfig /release
        ipconfig /renew
        NETSH winsock reset catalog
