Can't see my local site on ios device

Hi there!

Edge inspect is installed, Chrome is running, iMac and iPhone are connected with each other - but I can't see the local site I opened on my Mac in the iPhone screen.

I opened the the website I am currently working on with chrome on my Mac and now it should appear on my iPhone screen, too. Shouldn't it? Other regular www-tabs are shown.

What am I missing?

Thanks,
