What did you do?

Create session failed:
session, err := cluster.CreateSession()
err is not nil.
I am able to connect to the same host:port via telnet, netcat, or golang net.Dial.

What did you expect to see?

Create session should succeed.

What did you see instead?

unable to create session: unable to discover protocol version: gocql: no response to connection startup within timeout

If you are having connectivity related issues please share the following additional information

Describe your Cassandra cluster

please provide the following information

• output of nodetool status

• rebuild your application with the gocql_debug tag and post the output

Would you please tell me how to rebuild your application with the `gocql_debug` tag ?

Some update:
If clusterConfig's timeout is set to more than 10000000600 as below:
cluster.Timeout = time.Duration(viper.GetInt64("cassandra.timeout"))
cluster.ConnectTimeout = time.Duration(viper.GetInt64("cassandra.timeout"))
then there is no timeout error.

Update:
This issue may be because that I didn't run:

ALTER KEYSPACE system_auth
    WITH replication = {
        'class': 'NetworkTopologyStrategy',
        '<datacentre_name>': <number_of_nodes>
    };

But why it succeeds when the timeout is set bigger?
Maybe it's because of Cassandra itself adn SDK cannot do so much.
Please feel to close it. Before that, I would appreciate if anyone could tell me
"Would you please tell me how to rebuild your application with the gocql_debug tag ?"

Something like "go build -tag gocql_debug your_app", but it will be changed with the PR #1755
