A certificate warning means the browser cannot normally validate the HTTPS connection. Establish the cause before sending a password, personal information or payment.
If you are visiting the site
- Check the address you entered, especially the domain name.
- Check your device’s date and time and install its updates.
- Record the exact message and incident time.
- Contact the site owner through a known channel if the warning persists.
Do not disable certificate verification or bypass the warning to sign in. On a public network, also check whether its sign-in portal requires authentication. Do not reuse your Nuagerie credentials there.
If you administer the site
Check that the certificate covers the requested hostname, has not expired and includes a correctly installed certificate chain. A DNS change, server migration or proxy can cause a different certificate to be presented.
For a service hosted with Nuagerie, send support the domain, message, time and recent changes. Never send the certificate’s private key in an ordinary support request.
What HTTPS protects
HTTPS protects data in transit and allows the server’s identity to be checked against its certificate. It does not guarantee that a site is free of malware or that its content is trustworthy. A free certificate can be suitable for a website; the choice depends on requirements and the available service.
A simple “Not secure” indicator on an HTTP page and an HTTPS validation error are different problems. Consult the official Chrome explanations for the message you encounter.
Restore a reliable connection for visitors
An HTTPS warning can interrupt a purchase, a form submission or access to a work tool. Our team can help examine the requested hostname, presented certificate and intermediate services, then identify the changes needed. This addresses the cause instead of asking visitors to ignore the warning.
For a Nuagerie-hosted service, send those details through your Client Area. When preparing a new website, domain change or migration, discuss certificate and renewal requirements alongside the hosting setup.
