How to Fix VPN 628 Error

After updating to Windows 11 Pro, I was receiving this error when trying to connect to my VPN: "the connection was terminated by the remote computer before it could be completed".

 

In reviewing the Event Viewer logs, I saw the following error: CoId={47DD9B6D-A8EC-0007-5147-DE47ECA8D701}: The user SYSTEM dialed a connection named VPN which has failed. The error code returned on failure is 628.

 

After an hour of troubleshooting (re: googling), I came across this page which worked for me and resolved the issue: https://documentation.meraki.com/MX/Client_VPN/Client_VPN_OS_Configuration#Windows_10.

Evidently, the error 628 vpn fiddled with my VPN > Properties > Error 628 vpn settings. I had to enable "Require encryption (disconnect if server declines)", error 628 vpn, and then select "Allow these protocols" > Unencrypted Password (PAP).

Note: You must repeat all steps below every time you try to connect to the VPN.

Create xl2tpd control file:

mkdir -p /var/run/xl2tpd touch /var/run/xl2tpd/l2tp-control

Restart services:

service strongswan restart # For Ubuntu 20.04, error 628 vpn, if strongswan service not found ipsec restart service xl2tpd restart

Start the IPsec connection:

# Ubuntu and Debian ipsec up myvpn # CentOS and Fedora strongswan up myvpn

Start the L2TP connection:

echo"c myvpn"> /var/run/xl2tpd/l2tp-control

Run and check the output. You should now see a new interface .

Check your existing default route:

Find this line in the output:. Write down this gateway IP for use in the two commands below.

Exclude your VPN server's public IP from the new default route (replace with actual value):

route add YOUR_VPN_SERVER_PUBLIC_IP gw X.X.X.X

If your VPN client is a remote server, you must also exclude your Local PC's public IP from the new default route, to prevent your SSH session from being disconnected (replace with actual value):

route add YOUR_LOCAL_PC_PUBLIC_IP gw X.X.X.X

Add a new default route to start routing traffic via the VPN server:

route add default dev ppp0

The VPN connection is now complete. Verify that your traffic is being routed properly:

wget -qO- http://ipv4.icanhazip.com;echo

The above command should return .

To stop routing traffic via the VPN server:

route del default dev ppp0

To disconnect:
