809 Error in L2TP VPN

What the heck happened? Running Windows 19028VB_release.191115-1325. I created a VPN connection about two weeks ago and entered the reg key per:

reg add HKLM\SYSTEM\CurrentControlSet\Services\PolicyAgent /v AssumeUDPEncapsulationContextOnSendRule /t REG_DWORD /d 0x2 /f
All was working and it just took about 2-3 seconds to connect. This afternoon, forget it! I have checked all settings ...even deleted and recreated the connection. Nothing but the 809 error in the Event Viewer.
I NEED this in order to work. HELP!

IPSec VPN eror 809 after Windows 10 upgrade

I found that a windows 10 service blocks L2TP/IPSEC VPN access.

If you go to services.msc

Find "Xbox Live Networking Services" and disable that service.

After I did that the VPN worked for me.

I have tried everything from adjusting firewall rules to adding the registry entry to no avail with Error 809.
