XDRIP no house with Nightscout

Good, to see if you can help me ...., this weekend I could make the Nightscout account with Heroku and Github.It turns out that the Nightcout URL reads on the PC through the Diabox application the glycemia readings (I put the URL in Diabox and see the readings on the PC with my Nightscout URL).
The issue is that I have downloaded XDRIP and when I put the NightScout URL does not recognize me ..... In the state of the Nightscout Folow tab system it puts me ... last state-& gt; ns entries Download was not succesfull: 401Unauthorized.
Can anyone help me?(The MV is a Samsung-Android)
Also ask which CD entered for the 1 time to XDrip I get the assistant of data origin .... I understand that I have to choose others and then Nightcout follower.Within settings in TB data I have put the NightScout URL.
The system I carry is Freestile.
Thank you so much

@Sete good night.You have to put the URL in the form:
https: //password@name.herokuapp.com/api/v1/
If you don't have password in Hetoku ... put it :-)

Antonio thank you very much, it has already worked as you say ..... Thank you very much for your help.
