Charts are no more displayed in Chrome

[meteoesine]

I am currently experiencing an issue where charts (on pages, blocks and plugins) are not displayed in Google Chrome.
It does not appear to be an isolated problem, as all our Meteotemplate websites show the same behavior.

The issue occurs in Google Chrome but it work correctly with Microsoft Edge. Is it likely related to Highcharts?

Since most users use Chrome, displaying our weather websites without charts, with spinners endlessly loading, is not a good look.

Any suggestions would be greatly appreciated.
Thanks in advance for any help!
