How to have a sub domain in WIX redirect to Shopify

Topic summary

A user wants to maintain their primary website on WIX while using a subdomain (store.valiantaircommand.com) to display their Shopify store with the subdomain visible in the browser address bar.

Initial Challenge:

  • Domain is managed through WIX
  • User attempted to follow Shopify’s manual domain connection guide
  • Struggled to configure DNS records without changing the core DNS to Shopify

Current Status:

  • User reports getting the subdomain to work
  • SSL certificate is not showing as secured (screenshot provided showing security warning)
  • As a temporary measure, user plans to revert the redirect back to a Shopify-managed domain until the SSL/security issue is resolved

Unresolved Issue:
The discussion remains open with the SSL certificate configuration problem unsolved.

We would like to keep our WIX website as our primary domain, however would like to make store.valiantaircommand.com be the primary store domain so that the web address for store.valiantaircommand.com be displayed in the address bar.

Is this possible, our Domain is controlled through Wix, I have tried the following:

However I cannot work out how to not change the core DNS to be shopify

I seem to have got it to work, but the certificate is not showing as secured:

for the moment, will change the redirect in Shopify back to a shopify managed domain
