Hi All,

Please excuse my limited knowledge . We have an application in .Net and the
backend database is Cassandra.We have deployed in our application into
production which is behing the Firewall. We have opened the 9042 Port from
our Webserver to the cassandra cluster. But again we are getting the below
error

We have a 5 node cluster and added the static routing to all the node for
port 9042 .

Do we need open some more ports as the connection is established but is
timed out

An early help is highly appreciated
