It seems that your server doesn't like the payload that is being sent. Would logging the payload too possibly give you insight into what is different between Android and iOS?

[Vinod Rai]

Response is coming on postman with same iOS request.

Add this level parameter to your logger and see if you see anything different. The server is choking on what is being sent.

install(Logging) {
   ...
   level = LogLevel.ALL
   ...
}
