Android request to server always error code 499

[boykoy96bg]

Can you tell me the cause ?
Server Version : (Server v4xx)

Client Version : (Android v4xx)
Send any request to receive the error code 499
The server works fine when calling postman

private Response makeServiceRequest(String urlFragment,
String method,
RequestBody body,
Map<String, String> headers,
ResponseCodeHandler responseCodeHandler,
Optional unidentifiedAccessKey)
throws NonSuccessfulResponseCodeException, PushNetworkException
{
Response response = getServiceConnection(urlFragment, method, body, headers, unidentifiedAccessKey);

responseCodeHandler.handle(response.code());

return validateServiceResponse(response);

}
