Bearer Token Authorization shows unclear error

New to APIs/Postman
1

I’m trying to use PostMan to post an “Bearer Token Authorization” request. But PostMan keeps showing below error. But I’m able to send the same request use Fiddler Composer.
---- Error Starts
Could not get any response

There was an error connecting to localhost:39619/api/v1/auth/test.

Why this might have happened:

  • The server couldn’t send a response:

Ensure that the backend is working properly

  • Self-signed SSL certificates are being blocked:

Fix this by turning off ‘SSL certificate verification’ in Settings > General

  • Proxy configured incorrectly

Ensure that proxy is configured correctly in Settings > Proxy

  • Request timeout:

Change request timeout in Settings > General

Hello @tannguyenit i have the same Problem how did you solve that Problem?

I have a Token from Azure GraphAPI. if i send the request without the token i get a Response with the token i get that error. I have a Proxy but if you send that request via PowerShell it works but with postman not. what could be the Problem
