If you have domains pointing to an incorrect IP address, then your online store will be inaccessible to your customers. Check your store's domains settings to make sure that the status of each of your domains is shown as Connected or Setup in progress:
For each domain that has a different status, you need to make some adjustments to your domain provider's settings to point to Shopify's IP address,
18.104.22.168, and to
shops.myshopify.com for any subdomains.

Access your domain’s DNS records.
In the A record field, enter Shopify's IP address:
Create an ALIAS or CNAME record that points your root subdomains to
