Connect to node with Database Manager

I want to run CQL in a database manager (CLion). So I want to connect to a node, but I can not get it to work. When running vanille Cassandra, I can connect. I tried connecting to 127.0.0.1:9160, but I get this exception:

> The specified database user/password combination is rejected: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /127.0.0.1:9160 (com.datastax.driver.core.exceptions.TransportException: [/127.0.0.1:9160] Channel has been closed))

`ccm status` output:

> Cluster: 'test'
> ---------------
> node1: UP
> node3: UP
> node2: UP

`ccm node1 ring` output:

> Note: Ownership information does not include topology; for complete information, specify a keyspace
