Why am I facing the NET::ERR_CERT_COMMON_NAME_INVALID error on my website?

Technical Q&A
1

Site has been working fine for 2 months. Suddenly, visitors to the site see this warning:

Your connection is not private.
Attackers might be trying to steal your information
NET::ERR_CERT_COMMON_NAME_INVALID

When I click on the “not secure” in the URL bar, it says “Certificate Invalid” issued to “*.myshopify.com”

What’s the way to resolve this? Like I said, setup was fine it was working for 2 months, then went down sometime over the last weekend. Nothing I can figure out. Using Godaddy as domain registrar and the A Record and CNAME were set up 4 months ago, worked fine, and seem correct as per the instructions.

the domain is azulmarr.com

Hi @marcela_marroqu

welcome to community.

I noticed various strange things on your website. First of all there is only 1 page indexed in Google, the home page, and it is indexed as HTTP and not HTTPS

Second and most important it seems that you didn’t define a CNAME on your DNS record on GoDaddy. You need to define a CNAME that point to yourstore.myshopify.com

Please follow this guide: Connect your third-party domain to Shopify manually

You need to follow the guide of my previous post. First all you need to setup the CNAME.

That should fix the NET::ERR_CERT_COMMON_NAME_INVALID error that is caused by an invalid SSL certificate.

Hi, @creativenb !

Thanks for joining this thread.

I checked out your website and I cannot replicate this error and your website is appearing as normal on my end. Usually this error is browser related because the customer is using antivirus software or encryption. Please ask the customer to try another browser instead.
