Business website "https://roastery.stripe.dev/" is "Not a valid URL"

[jameshfisher]

The Stripe Connect flow asks for my business website. My business's website would be hosted on the Roastery platform, so I entered https://roastery.stripe.dev/. Surprisingly this gives the error "Not a valid URL".

It seems to ban any URL with a domain ending in stripe.dev or stripe.com.

Maybe good reasons for this, but if so, the demo should be on a clearly non-Stripe domain, e.g. roastery.stripedemos.dev.

Specifically the demo gives me the business website https://roastery.stripe.dev/p/has-bean.

Interestingly, this settings page shows my "platform url" as http://roastey.com/p/has-bean, but this seems unimplemented?
