errors when I try to request an Auth Token:Tunneling socket can not be established, status code 407

errors when I try to request an Auth Token:Tunneling socket can not be established, status code 407



I went ahead and removed all of the headers from my request except for Content-Type : application/json.


Unfortunately, I am still getting the same errors when I try to request an Auth Token:


The following screenshot represents the response of 2 request, the 1st in which Use the system proxy was checked in the Postman settings and the 2nd in which Use the system proxy was unchecked.


Please let me know if anything else looks incorrect with my request.

@Prathibha.Mariyappa

From my finding, the status code 407 could be 407 Proxy Authentication Required.

Therefore, I have tested it with Fiddler Proxy by enabling Required Proxy Authentication. I got the following error when I didn't set proxy authentication in Postman.

From this information, the client should contact the local IT support team to verify the problem.
