Please note
that WebNMS do not have known issues in this process (In fact I tried
this today and could successfully start BE & deployed FE and connect
FE's application client to both BE & FE).
Hence please provide us the following to analyze the issue:
1. Logs in both the servers
2. Whether you
could successfully connect application client (from
startApplicationClient.bat of both FE_HOME/bin/ & BE_HOME/bin) to BE
3. What message you see in the client (either in java console / command prompt) when you see when the client fails to connect.
