"Your connection is not private"??

Hi wix friends,
I need some help regarding access my domain. When I try the domain int he address bar, the website shows the following information (I provide a screenshot), saying that

"Your connection is not private Attackers might be trying to steal your information from xxx.com (my site address) (for example, passwords, messages, or credit cards)…

The security certificate expired 2 days ago"

Does anyone know how to fix this?

Many thanks my friends! Need immediate help.

You would be better suited going through Wix Support about this issue as it is not a code issue.
