Camera is searching and searching

Hi!
Installed sucsessfuly, but the camera don't open.

Not working on iOS 12.3.1 (nor chrome firefox or safari)

Hi !
I have set up your project and tried it using my iphone, I wasn't able to see the camera. I tried it using safari, firefox and chrome but neither have worked at showing up any image.

By the way, it is working great on the browser of my laptop.

Any idea why it would not work ?

Can not read.

Barcode can not read.I use chrome version 67.0.3396.87 (Official Build) (64-bit)
