Sophia here from Shopify.
Do you have other A and CNAME records in addition to the ones you added from Shopify? If so, those need to be deleted. I checked whatsmydns.net and it indicates that the domain doesn't have an A record or CNAME record pointing to Shopify.
You may need to contact your domain provider for assistance with saving the records you mentioned (A record,
220.127.116.11 and CNAME record,
shops.myshopify.com). If you do reach out to the domain provider, feel free to share this document with them to explain what you need.
