SOLVED - Unable to validate credentials

Hi,

I can’t validate my credentials, i’ve read the documentation so much again & again.
I didn’t found something that could a reason why… I tried multiple times…

Is there a way to check the request ID by ourself ?
Can you tell me what to do to fixed this?

Thx a lot!
