Not Secure only on home wifi

Hello, i am confused about this. I purchased a VPS from Hostinger. Im using CyberPanel for my domains and sites.

The issue im having is when i go to the site i launched using my cell data, it says “secure” and even has the lock in the browser. Works fine, but when i turn my wifi on, it says “unsecure” and wont let me view the site.
