Express.js server not working

So, i have completely set my website, i have a local server, and I’m testing on it before deploy to production. I can access the website from local IP, I found this out searching on openlitespeed topics. When I access it, it gets me to the public folder, as i set on my app.js, but when i try to access the express.js routes, receive an error ‘CANNOT GET /(route_path)’. The server is running, cause the port is being used, and is also ‘unlocked’ on the firewall. Is there something else I need to do? Any more info…

NOTE: on the litespeed monitor, the ‘*:80’ listener is red, is it important? the website works ok on https.
