Hi,
Firstly, I didn't find any answer to my problem, but I've found some people who have the same issue.
This is my issue :
I did as the readme file says, both secret answer, proxy launched etc...
But the logs says :

18:40:08: Error:- Forbidden (ut) : invalid credentials
18:39:58: Error:- Forbidden (ut) : invalid credentials
18:39:49: Error:- Forbidden (ut) : invalid credentials
18:39:43: Error:- Forbidden (ut) : invalid credentials
18:39:26: Error:- Forbidden (ut) : invalid credentials
18:37:25: Error:- Forbidden (ut) : invalid credentials
18:37:18: Error:- Forbidden (ut) : invalid credentials

And :
