Need Reddis expert to solve problem in our servers

We have two node js based servers running the same application and we have web sockets for braodcast. we wanted to sync both node js server through reddis so both of them are aware of every new connection. We have linux red hat where our application is running and our reddis server with separate ip. While trying to connect, it is connecting to localhost not the ip of reddist. Need expereienced reddis developer to help and solve the problem
