How resolve this issue ? I want to connect with existing my domain
You are either putting in wrong domain OR you're perhaps running another shop on shopify which is already connected with your domain.
shopify name is this https://justvirtuous.myshopify.com/
& my Website domain is justvirtuous.com
The shop name
Same name issue ? shopify & website ..
Is it possible that you set this up with a different Shopify account? I would log out of Shopify and then try logging in with different / older email addresses.
i am new on shopify i never use before
