I am trying to connect to Azure vNET Gateway and I am not having success. It ends with ErrorCode = 720 ErrorSource = RAS. Anyone experienced this issue before for the following scenario?

* Azure vNET Gateway configured with Basic SKU.
* VpnStrategy is SSTP for Windows 10
* Authentication: Client certificate (self signed)
* Both the root and client certificates are in current user personal store. They are resolved ok.
* Root cert is stored in trusted root path of current user
* Root cert is saved in Azure vpn gateway user configuration without line breaks
* Don't wish to create other SKU to save $$ on poc
* Deleted all the WAN Miniport adapters and rebooted the machine with no success. They get recreated automatically
* I can't share certificates (root or client) in this forum since I am revealing the vpn gateway endpoint in the logs (for security reason)
