Image in adaptative card: problems in a Mac browser

Hi,

I have a running bot and I send an adaptative card with an image, hosted in a server. The image is displayed properly in Teams client, and in a browser in Windows, but it is not visible in a browser in Mac.

My image in the "image" item (adaptative card):

    "url": "https://d3ozk90589p36c.cloudfront.net/comun/download/collaborate_logo_square.jpg"

What can be my problem?

Thanks,

Diego
