SSL certificate expired: what it means and how to fix it

When a site's certificate expires, browsers stop the visitor with a full-page security warning, and most people leave. The check below reads your certificate from outside and tells you how many days it has left.

Your own result, checked now in your browser

The check runs from your browser and nothing is saved to an account. To keep it free and fair, Xovris counts checks for 25 hours without keeping the readable address and holds a result for 60 seconds; your browser remembers the last address you checked. What the check keeps, and fair use: Privacy · Terms

Why certificates expire

A certificate proves your site is really yours, and browsers only trust it for a limited time. Under the CA/Browser Forum's ballot SC-081, the longest a public certificate may last fell to 200 days on 15 March 2026, falls to 100 days in March 2027 and to 47 days in March 2029.

How to fix an expired certificate

Renew it with whoever issued it, then install the new certificate where your site is served. Most hosts and certificate authorities renew automatically using the ACME protocol; when automatic renewal stops, it is usually because a DNS record or a validation file changed.

Other certificate problems

A certificate for the wrong name, or one browsers do not trust, causes the same warning as an expired one. The check names which problem your site has.
