Which is the real domain of Firebase hosting? for Polish image

I have a problem using a custom domain on firebase hosting, which makes it impossible to use the polish image function. Not sure which is the real domain? So how do I set it up? Because I received the answer: My picture is not from the domain connected to Cloudflare.
