Request Content-Length was not available in raw request

Note: The Test is working fine with different environment

Given Specific environment 

When Request made 

Then no Content-Length was generated by soap UI pro in Raw tab

And Request Log contains error :

• 2018-07-04 22:47:50.123 - Error getting response; java.net.SocketException: Software caused connection abort: recv failed

 FYR:

But the same endpoint is working fine in different project under Soap UI Pro for the same environment

and the different between this projects are the Content-type headers are passed from Request - Header tab in case of working project

and for not working project Content-type headers are passed from Request tab directly

FYR:

Challenging things are the same suite working in different environment

and the same endpoint working in different project for the same step

Please support on sharing the area i should check to identify the challenge
