Insert <iframe> from BuienRadar not working

Dashboard

Hi Bakman, thanks for your responds,

The image does rotate and shows 6 rain radar images.
Each image represents 10 minutes.Lets say the iframe is loaded at 11 in the morning, it will show rain radar between 10.30 & 11.30.
But as long as the page is not refreshed, it will at 15.00, still show the images from 10.30 till 11.30.
Also, when I manualy trigger the time stamp in node red, it will not refresh the <iframe.
