Error - the certificate name is invalid or does not match the website

It’s possible you’re receiving the following error message:

Certificate name mismatch

Generally, there are two explanations for this.

  • Either the certificate has a Common Name that doesn’t match the domain name you’re visiting. (For example, you could be visiting, while the certificate has been issued for its subdomain
  • If the Common Name does actually match the domain name you’re visiting, and you use the Apache web server, there can be another explanation. Possibly, the web server’s server name or server alias has been incorrectly configured. Fix this by editing the Apache configuration files and try again.
