Server returned HTTP response code: 401

I followed the instructions from this site https://github.com/AzureAD/microsoft-authentication-library-for-java/wiki/Integrated-Windows-Authentication Unfortunately I’m getting 401 response code with this exception:

I’ve checked the user, scope, clientId and authorization and they are correct. When I run C# example with the same user, scope, clientId and authorization everything works fine.

What can be a reason of this problem ?
