Cal here from Shopify, thanks for reaching out to us. I'm sorry to hear that you're having trouble with your domain!
Is it a Shopify bought domain, or are you with a third party domain host like GoDaddy? If it's a third party domain, I'd suggest reaching out to your domain host, to make that none of the DNS records were disruppted. You can find the correct A and CNAME records here.
I'd be happy to take a look at the domain from our end, would you mind sharting it with me here?
Hi again @SIAO!
This error likely resulted from you not verifying the email address that you attached to the domain. Can you look for an email in your inbox that you used for this domain, and verify it? This will fix your issue. Let me know how it goes!
Hi again @SIAO! I have re-sent the verification email. Can you please use it to verify your email.
