Failed to fetch - Node.js?

Question

JavaScript

Hello. When I go, for example, through a browser to the address example.com:6470, I get "Hello World", listening to the port is started via express.

But when I try to make a request with a third-party script, either via fetch() or via request() to the same address, it sends a "Failed to fetch" error, what could be the problem?
