Trouble to connect Cassandra Nodes to each other
<p>I would like to start my first steps with Apache Cassandra and looked/read a lot of tutorials but i am unable to connect two Cassandra aplications to each other...
May some of you can help me...
I have 1 Windows 2012 Server running Cassandra 3.5 and a Ubuntu 14 running Cassandra 3.5, too. On both Servers, i can run the ./nodetool status and get the status that all is working fine on the own IP adress. This apears on both Servers. But the Cassandra Applications cant find each other.
Below you will find some snippets of the *.yaml Config.<br/>
====Windows Yaml config=====</p>

<blockquote>
  <p>class_name: org.apache.cassandra.locator.SimpleSeedProvider <br/>
        parameters: <br/>
            # seeds is actually a comma-delimited list of addresses. <br/>
            - seeds: "172.16.17.21,172.16.17.22" // these are my two internal IP Adresses (21=windows 22=Ubuntu)</p>
  
  <p>listen_adress: 172.16.17.21 rpc_address:0.0.0.0 broadcast_rpc_address
  172.16.17.0 and finaly SimpleSnitch</p>
  
  <p>This Config looks similar to the Ubuntu Config expect i set the
  listen_address to 172.16.17.22.</p>

<p>What do i wrong?
Did i forgot to make any preconfigurations on the Servers/Networks?
May some of you can help me please...
