Problem with Remote Access permisson

Hi!

I've problem I can't solve. I have Windows Server 2012 which is AD controller and is used as RADIUS server for Mikrotik VPN server. When I makePPTP, L2TP connections to router everything works fine and I get connection, but when I connect withSSTP it shows error that username or password is not correct or authentication method is not valid -

unless I tick in "Allow access" checkbox under User Properties > Dial-In.  for specific user  -Then it works

Any ideas?
