Indicator-weather doesn't fetch the weather-data

Indicator-weather doesn't fetch the weather-data. If a location was formerly defined, then the old data is shown. If a new location is added, then the data of the other location is shown. When one presses "forecast", a pop-up with "Forecast information cannot be fetched. Connection cannot be established". It is clear that even the current weather-information can't be fetched.
