How can I connect my existing domain to replace the Shopify sub-domain?

Shopify Discussion

Topic summary

Goal: replace the Shopify sub-domain (.myshopify.com) with an existing custom domain.

Current issue: attempting to connect the domain returns the error “Domain has already connected.”

Meaning of the error: the domain is already linked to another Shopify store/account, or possibly already added to the current store. It cannot be connected until it’s disconnected from the other account.

Available options: set a custom domain as the store’s primary domain. This can be a domain purchased through Shopify or a third-party domain you already own.

Requested details: share screenshots of the error and the Settings > Domains page, and specify the domain provider to guide troubleshooting.

Suggested actions:

  • Verify if the domain is already added to your store’s Domains settings.
  • If linked elsewhere, disconnect it from the other Shopify store/account.
  • Contact Shopify Support (24/7) to locate and release the domain if you can’t access the other account.

Status: unresolved; further information and/or support intervention is needed.

Hello @thespinwheel ,

Good day! Gina from flareAI app here to assist.

“Domain has already connected” is a message that appears in Shopify when you try to connect a domain to your store that is already linked to another Shopify store or account. This means that the domain is already in use and cannot be connected to your store until it is disconnected from the other account.

You may need to reach out to the Shopify support team for further assistance.

Hi there @thespinwheel

Welcome to the Shopify Community!

I understand you have some queries about domains on your Shopify store - I’d be happy to help you out here.

When you say that you want to remove the Shopify sub-domain, are you referring to the .myshopify.com domain that comes as standard with all Shopify stores? You can of course change this domain to a custom one, which you can either purchase through your Shopify admin, or you can use a third-party domain that you have purchased from another host.

You mentioned that you tried to connect an existing domain - is this a third-party domain that you are trying to connect to your Shopify store? If so, we have some helpful info here which explains the process involved. Who is the domain provider of the custom domain you are trying to connect?

From what you have described, it seems like you are seeing an error about the domain already being connected. This could be because you have already added the domain to your store, or as @flareAI suggested perhaps the message says that the domain is connected to another store?

Feel free to share some screenshots of the error, and also of the Settings > Domains section of your admin, and I would be happy to advise on the best next steps.

You can also feel free to contact our support team 24/7 via our help center here, and one of our advisors can access your store to take a closer look.
