Thank you for your email. There is indeed a bug in the "ndnpingclient.py" (<a href="https://github.com/named-data/mini-ndn/blob/ea2d5d6802ea671d07771423e3dcb6b949e972e7/minindn/helpers/ndnpingclient.py#L30" id="LPlnk689807">https://github.com/named-data/mini-ndn/blob/ea2d5d6802ea671d07771423e3dcb6b949e972e7/minindn/helpers/ndnpingclient.py#L30</a>)</div>

in the above line doesn't seem a correct one, that is why you are getting the no-route nack. </div>
