Can't display image with HeroCard in MS Teams

I created a bot using botframwork and created a HeroCard. in web chat it work fine, but in MS Teams the image isn't presented. Any idea what could be the problem?

        var heroCard = new HeroCard
        {
            Title = "title",
            Subtitle = "sub title",
            Text = " some text",
            Images = new List<CardImage>()
            {
                // some image for example
                new CardImage("https://upload.wikimedia.org/wikipedia/commons/a/a3/June_odd-eyed-cat.jpg")
            },
        };
