I tried out the code that you have posted above and managed to retrieve data for the coordinates specified (7.619019,47.582084,8.519897,48.451066). There doesn’t seem to be anything wrong with the code you have posted. The server response message you are getting could be caused by your instance in your dashboard having some Map bounds specified, and you are querying data outside the bounds.
You could either check the map bounds (see screenshot below) or you could try with a new Configuration in your dashboard (you can base it on the Sentinel 2 L1C template).
