Stream - Doesn't always load first time


I have several cameras working successfully on stream. However, I find that when I load one of the several pages I have them on in lovelace on Hassio, they don’t always load first time. Some pages have two picture glace cards with a camera on each and one will load from one and not the other and vice versa. I often have to refresh the page in order to obtain both images.

I’m using a tinkerboard.

Does anybody know if there’s any changes to the configuration that will remove this issue please?

Thanks in advance
