I got a warning in Google Search Console about SNI. What should I do?
Google has detected that the current SSL/TLS certificate used on https://www.domain.com/ does not include https://www.domain.com/ domain name. This means that your website is not perceived as secure by some browsers. As a result, many web browsers will block users accessing your site by displaying a security warning message. This is done to protect users’ browsing behavior from being intercepted by a third party, which can happen on sites that are not secure.
Update your certificate
To correct this problem, either update your current certificate to add your domain name to the list of domains protected by the certificate, or get a new SSL/TLS certificate for your domain. The certificate should be issued from a Certificate Authority (CA) that is trusted by web browsers.
