Error while registering a shop (Testing environment)

@scriptfarm‍ i’ve tried your suggestion, but when entering https://domain.com or http://domain.com in the domain field it gives me the error that this isn’t a valid web address.

I’ve also tried www.domain.com but this also doesn’t work for the verification.

I would think that i’d need to whitelist a certain ip address so it can access the page since this is a test environment, but I can’t find anything about this.
