RRAS service

I'm getting this error message: the connection could not be established because the authentication protocol used by the RAS/VPN server to verify your username and password could not be matched with the settings in your profile.

Setup using:  SSTP on a Win10 workstation Under Security Tab for VPN connection, the protocols allowed are MS CHAP v2.

It connects, looks like it's about to connected and then I get the above error message. Tried about 10 times to no avail.

Thanks,

PAP was the correct protocol, I was using "Allow" CHAP but finally got it after numerous attempt.

Alas after 20 mins... I finally tried PAP and sure enough it worked. Was using Allows Protocols CHAP.  

Was getting impatient.

Thanks!

For the record; PAP is a rather insecure, old, option, the password is unencrypted.  You may want to revamp the system
