Hi Gabriel
Can you test where the connection is failing? It would help us isolate the
problem:
1) are the server and client on the same machine? Or over the network?
2) did the server receive the client's multicast query? Was it over IPv6?
3) did the server reply? Was the reply empty ("come talk to me in secured
mode") or did it contain a reply with the resources? If it contained a
payload, can you check with IoTivity logging enabled to see which IP addresses
it reported in the "eps" field?
>From your description, it looks like all of the above should be working. Then
4) what IP address did the client attempt to initiate a connection to? Does
that IP address show in "ipconfig /all" ?
>From your description, it sounds like we included an IPv6 address from an
interface that wasn't active, so the client attempted to connect to it and
failed. It could also be a link-local address coming from the wrong interface.
