This error means Chrome doesn't trust the certificate authority (CA) that issued the website's certificate. Ensure your system's date and time are correct. Clear your browser cache and cookies. If the problem persists, the website's certificate might be genuinely invalid, or your system's root certificate store might be outdated. Updating your OS can help.
