Ran the netstat command and got the following output: below command is working for me check it once.

netstat -an | grep 9042 tcp 0 0 ::ffff:10.1.22.10:9042 :::* LISTEN The above output indicated that we are listening on port 9042 and IP address 10.1.22.10.

However, the error clearly showed that cqlsh was trying to connect to 127.0.0.1 by default. So we were getting "connection refused" error.

Modified the cqlsh command to connect to the IP address 10.1.22.10 and re-ran it as follows and we were able to connect to Cassandra database successfully.
