I have implemented your Module, the MM2 is starting and then nothing happens.

Loading weather…

Can you tell me what is wrong in my config?
It doesn’t work with your location and nor with my location lon, lat and asl values!

                {
                        module: 'MMM-meteoblueCurrent',
                        position: 'top_right',
                        config: {
                                apikey: 'xxxxxxxxxxxx', // my personal api key is new and has 12 numbers or letters
                                city: 'Oberrieden',
                                lat: '47.2744',
                                lon: '8.5784',
                                asl: '464'
                                }
                },

the log of mm2 tell me nothing is wrong. All other forecast modules are working:
