Great question — answering as the UphillTech team:
may be it could help those who has this issue. I have found that the default region used in the exemple code was "US1" and that I have create my API KEY in the region "IE1". Creating and using an API KEY made in the US1 region has resolve my problem and has made the exemple code work. Now because I am in Europe region, i will try to figure how to set the default region as "IE1" in the SDK.
