What is the issue you’re encountering

I am trying to setup shopify with cloudflare and configure the DNS in order to use workers to route my traffic, but I am unable to setup DNS. I have followed O2O guide to setup. Cofig: “c name - @ - shopifyurl - proxied”, “c name - www - shopify - proxied”.

What steps have you taken to resolve the issue?

I have followed the O2O guide for shopify and also implemented solution posted in Discord.

What feature, service or problem is this related to?

So you have created 2 CNAME records with the names @ and www and the value shops.myshopify.com?

Right now, your shop works for me. Did you make any changes?

3

Yes, In my shopify domains www.mcgrocer.com redirects to mcgrocer.com. Right now I have restored the DNS config back to using A records, hence it is working.

4

So you have created 2 [CNAME] records with the names @ and www and the value shops.myshopify.com ?

Yes.

5

Could you make the changes again for a moment and then perform a trace to see if there are any problems?

I have updated it and here’s a screenshot:

It seems you have created the wrong CNAME records, please ensure you’re pointing at shops.myshopify.com. Nowhere does it say to use your own shops address for the CNAME.

Oh, ok. I misunderstood that.

Is this a live website where the downtime hurts you or can you leave it like this for a moment?

Yes, I have changed it back to A record, I can’t take the site down for long time.

I can for 15-20 mins

If at all possible, I would recommend that you contact the account owner and have them perform a trace (https://dash.cloudflare.com/?to=/:account/trace) after you make the change again.

Could you just quickly check if using DNS-Only CNAME records work or have the same error?

Could you just quickly check if using **DNS-Only** [CNAME](https://community.cloudflare.com/t/adding-dns-records/52718) records work or have the same error?

DNS only works for mcgrocer.com
Not working for www.mcgrocer.com

I was about to recommend that you create a support ticket, but a Cloudflare employee has already read this and confirmed this looks like a CF issue, so they’re looking into it.
