cassandra.cluster.NoHostAvailable

[Abhi5h3k]

I'm getting this error:

Django settings:

DATABASES = {
     'default': {
         'ENGINE': 'django_cassandra_engine',
         'NAME': 'practice',
         'TEST_NAME': 'practice',
         'HOST': '10.71.19.90',
         'OPTIONS': {
             'replication': {
                 'strategy_class': 'SimpleStrategy',
                 'replication_factor': 1
             }
         }
     }
 }

During handling of the above exception, another exception occurred:

If I'm missing something, kindly guide me on how to properly connect to Cassandra using django-cassandra-engine
