can't get city id nor weather data

Hello,
I installed today this plugin into my website fewo-traumstrand.de and I’ve got the API key from Openweather and paste it into the settings field. Actually I searched for the town Dranske and I found also the ID 6548410 for this town but it wont work at all. I wrote the Name into the name field and additional the ID in the ID field. I tried out also different cities like London or Berlin but it doesn’t run. Finally I changed the API key and also emptied the cache many times but it doesn’t run. What could be wrong?
with kind regards from Germany
