Describe the bug (be clear and concise)

Proxying from one localhost port to another localhost port doesn't seem to work.

Step-by-step reproduction instructions

app.use(
    "/api/organization/v1/organization",
    createProxyMiddleware({
      target: "http://localhost:8000",
      changeOrigin: true,
      pathRewrite: {
        "^/api/organization/v1/organization/": "/api/organization/v1/organization/",
      },
    })
  );

Results in:

[HPM] Error occurred while proxying request localhost:3000/api/organization/v1/organization/9db5e2af-81a1-476c-8ddb-45168e02fc6e to http://localhost:8000/ [ECONNREFUSED] (https://nodejs.org/api/errors.html#errors_common_system_errors)

Expected behavior (be clear and concise)

The request is proxied.

We meet this issue also, try to set the target url with '0.0.0.0' or '127.0.0.1' instead of 'localhost'
