Hi ,
>>Also tried disable firewall.
Have you tried to disable firewall on both VPN client and VPN server ? If it still doesn't work, what's the error message when you cannot connect to VPN?
It seems that there might be some early adopter issues at this time with Windows 10 2004, if possible, I would recommend you wait a bit until Windows 10 2004 matures with future cumulative updates.
You can report this issue to Microsoft directly with the Feedback Hub app. The Feedback Hub app lets you tell Microsoft about any problems you run in to while using Windows 10.
