What SSL monitoring catches
An expired certificate turns your website into a full-screen browser warning. It also breaks API clients, mobile apps and webhooks silently. Automated renewal helps, until the cron job fails or the DNS challenge stops working.
UptimePush reads the certificate on every check and alerts you at 30, 7 and 1 day before expiry. It also flags certificates that do not match the hostname, incomplete chains and untrusted issuers.
- Expiry warnings at 30, 7 and 1 day, on every plan
- Hostname mismatch and chain errors
- Issuer and remaining validity shown on the monitor
- Works for any port, not only 443, with TCP + TLS monitors
Check a certificate right now
Use the free SSL checker to see the issuer, expiry date and days remaining for any domain, then add it as a monitor so you never have to remember to check again.
Domain expiry too
Certificates are not the only thing that expires. UptimePush also looks up the registration expiry of your domain and warns you at the same intervals.
