Connection Not Private Error

When I go to my site, I get an error stating that my connection isn't private. I created it with Hugo SSG. I'm assuming it's because of the SSL. I "created" the site using CyberPanel. Then just uploaded it from my machine. When I look at the SSL in CP, it states that the SSL doesn't expire for many years (lol). Is there a way I can go about this?
Thanks.
