DataStax Devcenter fails to connect to the remote cassandra db

Question

I've installed DataStax cassandra and it is up and running on my remote machine. Now I am trying to connecto via DataStax Devcenter but it fails.

Before posting this question I've read identical here: DataStax Devcenter fails to connect to the remote cassandra database

I went to cassandra.yaml conf file but start_native_transport: true option is not in my file. Where should I look for it? Also I've changed rpc_address to: 0.0.0.0.

UPDATE:

If I add start_native_transport: true into my cassandra.yaml it just crashes on Cassandra restart. Please refer a log below:

Thanks for any Help!

Double check the changes that you have made to your cassandra.yaml. This error usually happens when you forget to close a quote or something else that alters the ability of Cassandra to parse the yaml file. — Aaron

start_native_transport: true

should be there in cassandra.yaml if its not there then you should add it into cassandra.yaml and try after restarting the Cassandra server
