Requests to the server on the hosting do not work, what should I do?

Question

Express.js

I have a script that makes requests to the server, it is already in the database
When I developed the application everything worked, because it was local and I accessed localHost
But now I uploaded the site to the hosting and everything works on my device, but not for others (error in the photo)
How do I contact the server? (not via localhost)

Answer 1

Haha! I did not expect that someone would bring the classics from a joke to life.
Raise the database on the server and connect to it
