Windows 10: VPN Connection Failing Error Code: 0x800704d4 CMROUTE.DLL - Need Assistance

Hello Team I’m facing an issue while trying to connect to a VPN. Despite extensive troubleshooting, I’m unable to establish a connection, and I’m consistently receiving error code 0x800704d4 and CMROUTE.DLL to update your routing table. Troubleshooting Steps Already Performed: Removed all third-party antivirus software and restarted the PC. Deleted the existing CHILD certificate and the old VPN client.

L2TP VPN on Lumia 950 giving error code 812

Hello,

I recently purchased a Lumia 950 (AT&T running Windows 10 Mobile build 10.0.10586.0.

When I configure my work IPSec L2TP VPN connection on my phone and then attempt to connect, it attempts to connect, then fails displaying the error:

The VPN connection failed with error code 812.

This seems to happen after the credentials are accepted.

During the connection attempt on the phone, the status display progresses as follows:

• Connecting to <address of my VPN server>
• Verifying your credentials
• Connecting to <address of my VPN server>
• The VPN connection failed with error code 812.

When I look at the logs of my VPN server, a connection is actually established successfully by the client, then immediately terminated.

I'm not positive who is terminating the connection on who (client or server).

VPN Settings configured on the Lumia 950 are as follows:

Connection name: My Work

Server name or address: <address of my VPN server>

VPN Type: L2TP/IPsec with pre-shared key

Pre-shared key: <pre-shared key that is configured on my VPN server & working on other devices>

Type of sign-in info: User name and password

I have typed the username & password in again multiple times to confirm it is correct. It is.

Furthermore, I have a Lumia 925 running Windows Phone 8.1. It connects perfectly using these same settings.

It seems something changed in Windows 10 Mobile that caused this VPN connection to stop working.

Do you have any suggestions on how I might be able to get this resolved?

I really need the VPN to be working.

Thanks!
