jpos Gateway : Not able to send back the response message received from the remote host to the client requested - jpos

Question

I am new to jpos. trying to use jpos-2_1_3 out of the box. I can see the message forwarded to remote host and response back but the response message is not delivered to the requested client.Getting the below error
[HOST_UNREACHABLE] o.j.t.p.QueryHost.expired:111 'mux.rsc' does not respond
I checked the client status which is connected and waiting for the response
My config files are as below

Answer 1

To summarize in an answer what was explained in comments, problem was field 11 not being matched by response. Because of that the mux didn't know that the incoming message was a response for the request.
You can see default fields used to match responses to requests by QMUX, and learn how to configure a different set of keys in jPOS programmers guide section 8.3.2
