cqlsh not connecting when configuring a two node cluster on windows server - cassandra

Question

I am trying to configure a two node cluster with cassandra in windows r2 2008 So i installed cassandra community version in one server (10.xxx.0.1,10.xxx.0.2) And then I stopped the service and then edited the configuraton.yaml file in the conf folder.
The changes are:
cluster_name
commented the num_tokens
gave the tokens in initial_token,
seeds as 10.xxx.0.1,10.xxx.0.2,
listen_addresses are their respective ip addresses which are 10.xxx.0.1,10.xxx.0.2,
rpc_addresses are same as listen_address,
endpointsnitch as gossip
I also changed the cassandra rackdc.properties file to dc=DC1 rack=RAC1.
and changed the cassandra-env file - uncommented: JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=10.xxx.0.1
I then saved and started back the service and ran nodetool status and got
Datacenter: DC1
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
-- Address Load Owns (effective) Host ID
Token Rack

and opened the cqlsh, but it is not connecting. Below is the error:
