SSL certificate errors in the browser
"Your connection is not private", expired or wrong-name certificates.
Check the site with our SSL checker: it says exactly what's wrong.
| What you see | Usual cause | Fix |
|---|---|---|
| Certificate expired | Renewal failed | On IDX hosting, run AutoSSL again (guide); on a VPS run certbot renew |
| Certificate for a different name | The certificate doesn't cover www or the subdomain | Make sure the name points to your hosting, then re-run AutoSSL |
| Not trusted / incomplete chain | Intermediate certificate missing | Install the full chain (CA bundle) (guide) |
| Padlock missing, no error | Mixed content | See Fixing mixed content |
Also check the date and time on your own device: a wrong clock makes every certificate look invalid.
