cassandra 3 node cluster on AWS loading data timeout

I'm loading data from csv files to a cassandra cluster using cql but I keep getting this error:

<ErrorMessage code=1100 [Coordinator node timed out waiting for replica nodes' responses] message="Operation timed out - received only 0 responses.">

when I do a nodetool status...I get this:

[root@ip-10-205-116-141 bin]# ./nodetool status

Note: Non-system keyspaces don't have the same replication settings, effective ownership information is meaningless

when I do a nodetool info on one node, I get this back...

[root@ip-10-205-116-141 bin]# ./nodetool -h 10.205.119.47 info
nodetool: Failed to connect to '10.205.119.47:7199' - ConnectException: 'Connection refused'.
