MongooseIM REST API's not working for POST requests - api

Question

Have anyone tried the MongooseIM 2.0.0 Bets services to hit web services.
I am able to to the GET calls as defined in this Swagger site link but unable to get the POST request as it gives me error for the same data that I use with my IP address instead of localhost.
Here in my Mongoose Im error response.

This was probably answered here: https://github.com/esl/MongooseIM/issues/1055 already. Am I right?
