Requester can see the Responder but dont send request to it

[boygiandi]

I have a weird issue:

2 Responders (same code) are running at 2 servers (server A and server B).

If I run the Requester from My local macbook, I can see the response from A and B round-robin
But when I run the Requester from another server, I only see the response from server A. Server B got no message.
If I stop Responder at server A, server B still got no message.

I use redis for discovery and I can see every process can see other process fine. The Requester can see the Responder at server B but don't send message to that server :(

Sorry, somehow my Responder server cannot connect to server B. Change server and everything works fine
