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,
R

Do you know what the requirement on the server is. In short, the issue is that the settings you have on the client side does not match the available options on the server/

try chap and or pap and see if that works.

Use the old control panel interface to get to the networking and sharing .....

chap is possibly the correct option.

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

While pap is insecure in its own, the sstp tunnel sets up first so the credential transmission is within the encrypted tunnel..

Though it would require a change on the server side.
