Your certificate expires soon
TLS certificate nearing expiry
What this means
The certificate your site uses runs out shortly. On that day browsers stop opening the app and show a warning instead — there is no grace period.
Why it matters
This is the rare problem with a known date attached, and it still takes sites down regularly: renewal is usually automatic, and nobody notices it stopped working until the morning the site goes dark. Fixing it afterwards takes minutes; explaining the outage takes longer.
When this is not a problem
Short-lived certificates renewed automatically every few weeks are normal — check that renewal actually runs rather than the remaining days.
How to fix it
- Renew the certificate and confirm the automatic renewal actually completed.
- Add a reminder that fires well before expiry, so a broken renewal is noticed while there is time.
Prompt for your AI agent
Renew the site's TLS certificate and verify that automatic renewal runs and succeeds well before the expiry date.
How to verify the fix: check the certificate expiry date in the browser — it should be months away
