I’m having the same experience as optimator (“Failed to locate node”, CB 1.8 on CentOS, .net lib 1.1.6). My config is:
I can browse to the resource in a browser from the client host. Running tcpdump on the CB server is silent, telling me that the .net client lib isn’t sending one packet to the server (though I see traffic of course when navigating with the browser). Firewalls are disabled on both client and server hosts.
Browsing the source of the client lib, it appears that a node for the given key can’t be identified in the server pool. I can’t successfully build or debug the lib, though, so the trail goes cold.
Any help would be appreciated.
