How to fix ssl cert expiring soon on BigCommerce
Renew your SSL/TLS certificate before it expires to keep your store secure, trusted, and visible in search results.
Steps for BigCommerce
- BigCommerce automatically provisions and renews SSL for all storefronts using the built-in shared certificate — no manual action needed for the default subdomain (*.mybigcommerce.com).
- For a custom domain: go to BigCommerce Admin → Store Setup → Store Profile → SSL Certificate. BigCommerce auto-provisions a free Let's Encrypt certificate when your custom domain's DNS is correctly pointed to BigCommerce.
- If the certificate shows as expired or invalid, go to Server Settings → Store Profile, remove and re-add the custom domain to trigger re-provisioning.
- If you have purchased a dedicated/EV certificate, upload the certificate files under Store Setup → SSL Certificate → 'Upload Certificate' and enter the private key, certificate, and CA bundle.
What is ssl cert expiring soon?
An SSL/TLS certificate is the digital credential that proves your website is who it says it is and encrypts the connection between your store and your customers' browsers — it's what puts the padlock icon and "https://" in the address bar. Every certificate has an expiry date, after which browsers will show a full-screen red warning ("Your connection is not private") to anyone who tries to visit your site. Renewing means getting a fresh certificate installed before the old one runs out. Most certificates last 90 days to 1 year, and renewal should be started at least 30 days before expiry to allow time for any issues.
When your certificate expires, every major browser — Chrome, Safari, Firefox, Edge — will block visitors with a hard security warning before they even see your store. This instantly destroys trust and conversions: most shoppers will leave and never return. Google also uses HTTPS as a ranking signal, so an expired certificate can hurt your organic search visibility. If you collect any customer data (names, emails, payment info), operating without a valid certificate exposes that data to interception and puts you at legal risk under privacy regulations such as GDPR and PCI-DSS. Even a single day of expiry can cause lasting damage to your brand reputation.
