SSL certificates: what happens when they expire
HTTPS is a lock on the browser. When the certificate expires, visitors see scary warnings—and many leave.
SERP for “ssl certificate expired” centers on browser warnings, lost trust, and renew/install steps.
What CrowWake checks
We open TLS to your domain on port 443, read the certificate end date, and report days remaining. Expired = fail. Under 21 days = warn. We also note the TLS protocol version we negotiated.
Why it matters
Auto-renew fails more often than people admit (DNS challenges, paused cards, forgotten staging hosts). Agencies managing many certificates need a rooster, not a calendar spreadsheet.
What “good enough” looks like
Valid cert covering the hostname users type. Renewal automation tested. Plenty of runway before expiry.
If CrowWake crows
Renew and reinstall (or fix ACME automation). Verify the live hostname—not only a CDN origin—matches what customers use.

Add the domain, leave the boxes checked, and the flock will crow when this drifts.
