Pictures don't work on tablet and phones

I have a basic Picture Entity Card and a picture stored locally and exposed using the instructions. And it works on any computer web browser that opens my homeassistant session.
But it simply will not work on any tablet or iphone, neither in the browser or the homeassistant app. Pictures stored on the web will work. can’t wrap my head around what’s going on here. Does it have anything to do with http/https? Or internal IP vs external? Any ideas anyone?

Did you try refreshing the brwoser cache om these devices? Are accessing it over the same address as from the devices it is working?

Hmmm, turns out it’s a basic http/https issue, which I was absolutely certain I had tested.
