Temporarily you must disable SSL protocol in the awesome-weather.php file on 19 line:
define( ‘AWESOME_WEATHER_OWM_API_URL’, ‘https://api.openweathermap.org/data/2.5/’ );
set https:// instead of https://
define( ‘AWESOME_WEATHER_OWM_API_URL’, ‘https://api.openweathermap.org/data/2.5/’ );
It worked for me.
