  <p>When i try to connect to Cassandra server it shows an error <code>All host(s) tried for query failed (tried: 90.43.255.66:9160 (com.datastax.driver.core.exceptions.TransportException: [null] Cannot connect)).</code> When i connect to local system by changing ip to <code>127.0.0.1</code> its works fine. </p>
