"Could not get any response" response when using postman with subdomain

Question

First Go to Settings in Postman:

1. Off the SSL certificate verification in General Tab:

2. Off the Global Proxy Configuration and Use System Proxy in Proxy Tab:

3. Make Request Timeout to 0 (Zero)

Configure Apache:

If above changes resulted in 404 response, then continue reading ;-)

Users that host their site locally (like with XAMP and/or WAMP), may be able to visit their virtual-sites using https:// prefixed address, but it's a lie, and to really enable SSL (for each virtual-site), configure Apache like:

• Open httpd-vhosts.conf file (from Apache's conf/extras directory), in your preferred text-editor.

• Change virtual-site's settings, into something like:

  <VirtualHost *:80 *:443>
      ServerName my-site.local
      ServerAlias *.my-site.local
      DocumentRoot "C:\xampp\htdocs\my-project\public"
  
      SSLEngine on
      SSLCertificateFile "path/to/my-generated.cert"
      SSLCertificateKeyFile "path/to/my-generated.key"
  
      SetEnv APPLICATION_ENV "development"
  
      <Directory "C:\xampp\htdocs\my-project\public">
          Options Indexes FollowSymLinks
          AllowOverride All
          Order allow,deny
          Allow from all
      </Directory>
  </VirtualHost>
  

  But of course, generate a dummy-SSL-certificate, and change all file-paths, like from "path/to/my-generated.cert" into real file-addresses.

• Finally, test by visiting local-site in browser, but using http:// (without S) prefixed address; Apache should now give error like:

  Bad Request
  
  Your browser sent a request that this server could not understand.
  Reason: You're speaking plain HTTP to an SSL-enabled server port.
  Instead use the HTTPS scheme to access this URL, please.
  

I had the same issue. It was caused by a newline at the end of the "Authorization" header's value, which I had set manually by copy-pasting the bearer token (which accidentally contained the newline at its end)

If you get a "Could not get any response" message from Postman native apps while sending your request, open Postman Console (View > Show Postman Console), resend the request and check for any error logs in the console.

Hi This issue is resolved for me.

setting ->general -> Requesttimeout in ms = 0

If all above methods doesn't work check your environment variables, And make sure that the following environments are not set. If those are set and not needed by any other application remove them.

HTTP_PROXY
HTTPS_PROXY

For me it was the http://localhost instead of https://localhost.
