Postman Error: tunneling socket could not be established, statusCode=407

Question

I am using the desktop version of Postman at a client site to test an API. However, I am unable to access any SSL sites in Postman, such as the Git Hib API: https://api.github.com/users/karlgjertsen

However, I can make the same API call through Chrome, so this is Postman specific.

I assume it is down to proxy settings, but I am not sure how to view or update these in Postman. Has anyone had any experienced something similar?

Answer 1

I turned OFF both Global Proxy Configuration and Use System Proxy in Settings->Proxy tab in Postman and it started to work.

Answer 2

This solved my issue :

The option "Respect HTTP_PROXY, HTTPS_PROXY, and NO_PROXY environment variables." was selected by default in the proxy settings. I turned off this option and it worked for me.
