Connection refused for every call

[Makistos]

httpyac looks exactly the kind of tool I have been looking for. I've used REST client in VS Code but it doesn't support automation so it's usefulness is limited.

So I was delighted I found httpyac but unfortunately it does not work for me at all. For instance I have this is my test.http file:
GET http://localhost:5000/api/magazines HTTP/1.1

Running that call with curl or with the REST client works, but with httpyac I get this:

{
  url: 'http://localhost:5000/api/magazines',
  protocol: 'HTTP',
  method: 'GET',
  headers: { Accept: '*/*', 'User-Agent': 'httpyac' },
  options: {
    cookieJar: CookieJar {
      rejectPublicSuffixes: undefined,
      enableLooseMode: false,
      allowSpecialUseDomain: true,
      store: { idx: [Object: null prototype] {} },
      prefixSecurity: 'silent',
      _cloneSync: [Function (anonymous)],
      _importCookiesSync: [Function (anonymous)],
      getCookiesSync: [Function (anonymous)],
      getCookieStringSync: [Function (anonymous)],
      getSetCookieStringsSync: [Function (anonymous)],
      removeAllCookiesSync: [Function (anonymous)],
      setCookieSync: [Function (anonymous)],
      serializeSync: [Function (anonymous)]
    },
    hooks: { beforeRedirect: [Array], beforeRequest: [Array] }
  },
  proxy: undefined
}

  },
  handled: true
}

And I can see that the call never went to the backend. What is causing this?

Can you try to call something like postman echo?

GET https://postman-echo.com/get

Is your server reachable with http://localhost:5000 in Browser/ curl?

[Makistos]

Yes, it returns the front-end. This is the old UI written in Flask, my new UI uses the same codebase as just the backend.

That Postman request does seem to work. This also works if I change localhost to my production domain.

I also tried to run the Flask app with flask run instead of running it from VSC -> no change.

Ah! But now I figured it out, for some reason I have to use 127.0.0.1 instead of localhost in this case.
