Often after a restart and sometimes just during the day my picture-entity cards with video feeds end up looking like this:
It happens with any camera source including local_file so it’s not a problem with the feed.
If I refresh the page they usually show up, but it’s annoying having to refresh my tablets several times/day to get the feed to show up.
It happens on multiple devices and browsers. Wireless or wired.
Yup, same here. Been seeing it through several versions of HA since long ago. I originally thought it might be the picture source, but Blue Iris is pretty good about providing this image all the time.
