BigCommerce SSL Certificate Not Working

Workaround available BigCommerce Updated November 13, 2026Based on 2 user reportsHow we research

Quick answer

BigCommerce applies free SSL automatically once the custom domain points to the store. If it does not appear, missing DCV CNAME records are the usual cause; there is no manual install.

Most likely fix: Confirm requirements

How to fix it

Try these in order — the most common fix is first.

  1. 1. Confirm requirements

    1. Store must be on a paid plan with a custom domain
    2. Check the domain is pointed with an A record, CNAME or BigCommerce nameservers
    Did this fix it?
  2. 2. Add the DCV records

    1. If you use A or CNAME records add a CNAME for _acme-challenge.yourdomain.com using the target shown in BigCommerce's Free SSL article
    2. If the store uses www also add _acme-challenge.www.yourdomain.com
    3. Keep your DNS host's default TTL

  3. 3. Wait and recheck

    1. Allow up to 48 hours for propagation
    2. Check records with an online DNS lookup
    3. Remove conflicting records and CDN proxies on those hosts
    Did this fix it?
  4. 4. Contact support

    1. If records were added after applying the domain, contact BigCommerce support with your domain
    2. There is no option to apply the certificate manually
    Did this fix it?

Symptoms

Why it happens

  • Domain not pointed correctly
  • DCV CNAME record added after the domain was applied
  • Missing second DCV record for the www host
  • DNS propagation still in progress (up to 48 hours)
  • Store not on a paid plan
