calling Jira create API from node js from AWS

Hi,

I've just built functionality in my Node.js app that allows me to create Jira issues via Jira API. I'm using simple login with e-mail address and token + 'request' library to make requests. It works great when I launch it from in my local environment but I keep on getting 401 - Unathorized when I deploy the app to AWS EC2. What could be the reason for this issue? Below is the example request that works when fired locally:

const headers = {
  'Authorization': 'Basic ' + Buffer.from(jiraUser + ':' + jiraPassword).toString('base64'),
  'X-Atlassian-Token': 'no-check',
  'Content-Type': 'application/json',
};

Select allOpen in new window

[code]router.get('/jira/priority', AuthGuard.verify, (req, res, next) => {
  request.get({url: jiraUrl + 'priority', headers: headers}, (err, resp) => {
    // logic
  });
});

Select allOpen in new window

[/code]

The only thing that was coming to my mind is the request origin, that might be different when firing requests from AWS.
