What is the MOST likely cause of a certificate error after installing a wildcard SSL certificate for a website?

Certificate misconfigured
Certificate expired
Certificate revoked
Certificate not signed

The correct answer is: Certificate misconfigured

When a wildcard SSL certificate is installed, a common cause of certificate errors is a misconfiguration in the certificate itself. A wildcard certificate is designed to secure multiple subdomains of a main domain, but if it is not set up correctly—for example, if the wildcard is improperly formatted (e.g., using an incorrect domain name or having an issue with the DNS configuration)—it will lead to errors when users try to connect securely to those subdomains. Misconfiguration can manifest in various ways, such as having the wildcard application applied incorrectly in the web server settings or failing to match the domain structure (the wildcard only covers one level of subdomains). A certificate misconfigured this way results in browsers treating the connection as insecure, prompting certificate error messages. In contrast, the other choices imply situations that typically do not stem from configuration issues. If the certificate were expired, revoked, or not signed, those would be explicit issues related to the certificate's status rather than its configuration. While such problems may also lead to certificate errors, they would suggest different underlying causes separate from configuration errors. Thus, the most probable reason for encountering an error after the installation of a wildcard SSL certificate is indeed a misconfiguration of the certificate itself.
