final int statusTest = responseTest.getStatus(); // here i get 204,because i make server return 204 then there is nothing.
String body responseTest.getAsString() // here i get empty which is correct.

Solution

Something caused a problem with the length of the response body of the previous HTTP request and damaged the pooled connection

The previous request is interpreted by okhttp as having no body, but it has this body:

{"Data":[],"Status":"success"}

It may be an error in the server or in okhttp, depending on the header and code sent by the previous URL If you can paste this failed request, we can find its error!
