# ERR_CERT_DATE_INVALID on Shopify

> Shopify issues and renews the certificate for you, so this almost always means a custom domain whose DNS still points somewhere else — Shopify cannot renew a certificate for a domain it does not control.

## Why it happens on Shopify

 Shopify issues and renews the certificate for you, so this almost always means a custom domain whose DNS still points somewhere else — Shopify cannot renew a certificate for a domain it does not control.

## The fix on Shopify

 In Shopify admin → Settings → Domains, check the domain shows 'Connected' with SSL 'Active'. If the CNAME still points at an old host, repoint it to shops.myshopify.com and wait for the certificate to reissue (usually under an hour).

## If that didn't fix it

 Shopify has its own failure mode, but ERR_CERT_DATE_INVALID has a wider set of causes. The most common one overall is: The certificate expired and auto-renewal silently stopped.

 Renew immediately. For Let's Encrypt, run the renewal manually and read the output — the usual cause is a failing HTTP-01 challenge after a redirect or firewall change.

## Check your own domain

 The SSL checker returns the exact notAfter date and days remaining for the hostname, which immediately separates 'genuinely expired' from 'your clock is wrong'.
