In the section "Certificates" in my GoDaddy account I read this message: No matching certificates. But when I check my site with Certificate Checker tool it appears that it has a certificate but there are errors: 1. Certificate Names - Hostname missmatch; 2. Heartbeat Extension - Enabled; 3.Strict-Transport-Security - Disabled.
With another SSL checker appears this message:
None of the common names in the certificate match the name that was entered. You may receive an error when accessing this site in a web browser.
