I have a VF page with custom css referencing some images in resources like this:
background-image: url(/resource/1265000000000/someImage);

I created a new dev sandbox and the page looks like expected. I expose the page in a lightning component via an Iframe in communities - this particular resource can not be downloaded images are missing.
JS console logs show
https://xxxxxxx.csxx.force.com/resource/1265000000000/someImage 503 (Service Unavailable)

On other sandbox the Iframe-community config works fine
What could be the reason? I don't see difference between the 2 dev sandboxes

If your community is mycommunity.com/support you need to use "/support/resource/13237000/resourcename"
