Uable to make a req from one server to another - "Error: Request failed with status code 401"

I am trying to make an api req from one server (localhost:3000) to another server(localhost:3001) but I am getting authentication error 401.

Note:If I hard code the authentication token, I am able to make the request.This let me conclude that I am not setting up the axios authentication header in a right way.

apiFile.ts file

import axios, { AxiosInstance } from 'axios';
import { Dispatch } from 'redux';
import { handleResponse } from './handlers';
import { getDiscussionsAction } from '../../redux/actions/dataActions';

  let axiosInstance: AxiosInstance = axios.create();

function addDiscussion(data:String) {
    axiosInstance.post('http://localhost:3001/api/addDiscussion',data).then(response=> {
    console.log(response)
  }).catch(error=>{
    console.log('error on adding post',error)
  })
}

function setupAxiosInstance(token: string) {
  console.log('inside setup Axios Instance')
  console.log('token setup Axios',token)
    axiosInstance = axios.create({
        headers: {
          Authorization: 'Bearer ' + token}
    });
}
export default {
    getDiscussions,
    addDiscussion,
    setupAxiosInstance
}

Expected: When I setupAxiosInstance(String) and pass token to it, it should set the header with the token for subsequent request.

Actual: Though I can see that setupAxiosInstance(String) method have received token and but in subsequent request (ex:AddDiscussion api req), it does not have the authentication

[. It works when I hard code the token in -'let axiosInstance: AxiosInstance = axios.create();' like

let axiosInstance: AxiosInstance = axios.create({
      headers: {
        Authorization: 'Bearer fjsdkf.sdjkfksfklsdjjksfshjdfhksndyrndbsjdjasbckcnbsdcb;efjdfnsdklncsncsln'}
  });)

And also if I do something like below, it still does not work either.

function setupAxiosInstance(token: string) {
  console.log('inside setup Axios Instance')
  console.log('token setup Axios',token)
    axiosInstance = axios.create({
        headers: {
          Authorization: 'Bearer ya29.Gl9uB4tmH0GzYyxBOmeICZa7vsNLZXPuj2du3Q4HIBMGQzZhixXWuS5mCNSPzkCzfjYK0-XNTM0bHI_Fmist9bjYU9CdD06ZtzHPs8TCHmAQcG1dryM8u9_LtfOHiaVGzA'}
    });
}

If anyone can pointout what I am doing wrong or point me in the right direction?, that would be great.

In case anybody faced this same issue.I was able to resolve the issue by using LinkContainer from react-router-bootstrap in my component (One of my friend figured it out. Kudos to him.).This was not an issue with axios header authorization but how I was navigating across my react components.

Issue: Though I could see the setupAxiosInstance(String) method have received token and but in subsequent request (ex:AddDiscussion api req), it does not have the authentication.

Reason: Everytime I was navigating to another link using href, there was a page refresh and it was deleting the header authorization.

Solution: 

import { LinkContainer } from 'react-router-bootstrap'

use LinkContainer for navigation

<Nav className="mr-auto">
        <LinkContainer to="/discussion">
          <Nav.Link >Discussion</Nav.Link>
        </LinkContainer>
      </Nav>
      <LinkContainer to="/add-discussion">
        <Button variant="primary" id="ask-a-question-button">Ask a Question?</Button>
      </LinkContainer>

or use push.history

<Navbar.Brand href="/home" className="Nav-link">Discussion</Navbar.Brand>
        <Nav className="mr-auto" onSelect={(selectedKey: string) => console.log('selected', selectedKey)}>
          <Nav.Link onClick={() => this.props.history.push("/home")}>
            Home
            {/* <Link to="/">Home</Link> */}
          </Nav.Link>

          <Nav.Link onClick={() => this.props.history.push("/login")}>
            Login
            {/* <Link to="/login/">Login</Link> */}
          </Nav.Link>
        </Nav>
      </Navbar>

but dnt use href to navigate 

<Nav className="mr-auto">
  <Nav.Link href="/Discussion">Discussion</Nav.Link>
</Nav>

Instead of reassigning the instance you can set the instance headers like this 

function setupAxiosInstance(token: string) {
  console.log('inside setup Axios Instance')
  console.log('token setup Axios',token)
  axiosInstance.defaults.headers.common.Authorization = `Bearer ${token}`;
}
