ICIT weather widget suddenly stopped working

Dear sirs
I’m using your ICIT weather widget in a site for almost a year, and it always worked well (now I’m using v.2.5.2).
But a few days ago it stopped working, with the message “An error has occurred with the ICIT Weather Widget, if the issue persists through refreshing please contact the site administrator.”
You can look it here: https://www.insardinia.ch/en/property/wonderful-villa-with-swimming-pool-in-cala-granu-porto-cervo/
I added a few rows in PHP code in order to print the URL I was calling and the server response (that is empty).
But if I open the same URL in a browser page the response is correct. I contacted the OpenWeather support and they told me that the request is well formatted and works well.
I am using the plugin in my local development environment too, and there all is working fine.
Could you please help me in finding the problem?
I can add debug lines in PHP code to print variables and arrays values, if you need them.

Thank you very much for your help
Riccardo
