Video tag not working on ios, android?

Question

HTML

I've already tried many options. one of the last

<video autoplay="true" muted="true" loop="false" playsinline="true" preload="auto" width="400" height="400">
              <source src="./images/content/3BLOK.mp4" type="video/mp4">
            </video>

And it doesn't work. In safari, it's just a white screen, as if there's nothing there. Black screen on android
