# Expired certificate for previews

Not so much a question as an observation. It looks like the certificate for the preview domain has expired, so blog previews are not working.

This should now be fixed – thank you for the report – funnily enough the issue surfaced because the server which handles SSL was too stable, and the lack of crash-restart cycles meant the updated certificates were not loaded from disk by NGINX. I have adjusted the SSL renewal script to automatically reboot NGINX so this issue should not resurface.
