The Why:
- To access a website, your web browser must run a check on the digital certificates that are installed on the website's server to make sure that the site is up to privacy standards and safe to proceed. If your browser finds something wrong with the certificate, it will stop you from accessing the site. This is when you’ll see the “Your connection is not private” message.
- A Secure Sockets Layer (SSL) Certificate is for serving websites over secure HTTPS connections. HTTPS is a security barrier used to safely authorize connections and protect data. An SSL error connection occurs when there is no secure way for your browser to open what you have requested. When the browser sees that the connection is not secure, it will try to stop you from accessing the website.
- There can be a few different reasons that a SSL connection error occurs:
- The certificate is missing or expired
- Your browser is not updated
- Your Mac's date and time settings are off
- There is an issue with the website's server
Since you provide no information about your Mac (other than it is a iMac Pro) or what you have tried so far to resolve this issue yourself, it will be difficult to offer you any potential solutions on how to resolve it.
