Strange camera issue

raspberry pi 3b with version 2.0 pi camera. Installation works fine and webcam displays properly on two different pc when accessed via webpage. Same page on my iPad Pro web page is a black box. Any ideas? Multiple browsers tried on the pad all display a black box. Seems like this is pad peculiar. I’ve tried two apps as well...octopod and octoclient. They also display black boxes.

Problem resolved - it’s just the pi WiFi range. Get the pad closer and it all works fine - the stream continues without issue once it’s started anywhere in the house but will not initiate unless the pad is closer to the pi. Strange.
