Renew your TLS certificate
Transport · about 15 min
In plain words
Your HTTPS certificate expires soon. When it does, every visitor gets a full-screen "Your connection is not private" warning.
What can go wrong
The site becomes effectively unreachable for visitors and API clients at the moment of expiry.
How to fix it

sudo certbot renew --dry-run # test auto-renewal
sudo systemctl list-timers | grep certbotCloudflare
SSL/TLS → Edge Certificates: Universal SSL renews automatically.
If your origin uses a Cloudflare Origin CA cert, check its expiry under SSL/TLS → Origin Server.cPanel
SSL/TLS Status → Run AutoSSLBefore you change anything: We read the expiry date from public Certificate Transparency logs, so a just-renewed certificate can take a little while to show up.
Check that it worked
Re-run the ProbeHunt check after renewal.
