Foglight REST API - Authentication error - "Method Not Allowed"


I am trying to access Foglight using REST API but it is throwing error "Method Not Allowed". 


I have Administrator and API access on my user. I tried with http://<server>:<Port>/api/v1 and it is returning response (in Browser and Postman client) but when i tried with http://<Server>:<Port>/api/v1/security/login?authToken=<authToken> it throws an error as "Method Not Allowed".

Since I am new to Foglight, need to understand if I am missing any configuration at Foglight Side OR am i doing this incorrectly?

Followed the Article: but with no luck.

Any Help would be much appreciated.

Regards, Ravi
