React Native iOS simulator

For some reason, on my iOS simulator while doing react native development, ImageKit will not serve images to the simulator.

Basically - going direct to s3 will work

        <Image source={{ uri: s3_url }}/>

but imagekit will not work

        <Image source={{ uri: imageKit_url }}/>

The same URLs will work in browser, and on an actual device.

but in the simulator they won’t load.

I had the same behavior with another image transformation provider - what is the root cause?
