我一直在尝试使用gocql连接cosmos cassandra数据库。

func GetSession(cosmosCassandraContactPoint, cosmosCassandraPort, cosmosCassandraUser, cosmosCassandraPassword string) *gocql.Session {
    clusterConfig := gocql.NewCluster(cosmosCassandraContactPoint)
    port, err := strconv.Atoi(cosmosCassandraPort)
    if err != nil {
        log.Fatal(err)
    }
    clusterConfig.Port = port
    clusterConfig.ProtoVersion = 4
    clusterConfig.Authenticator = gocql.PasswordAuthenticator{Username: cosmosCassandraUser, Password: cosmosCassandraPassword}
    clusterConfig.SslOpts = &gocql.SslOptions{Config: &tls.Config{MinVersion: tls.VersionTLS12}}

    clusterConfig.ConnectTimeout = 10 * time.Second
    clusterConfig.Timeout = 10 * time.Second
    clusterConfig.DisableInitialHostLookup = true

    // uncomment if you want to track time taken for individual queries
    //clusterConfig.QueryObserver = timer{}

    // uncomment if you want to track time taken for each connection to Cassandra
    //clusterConfig.ConnectObserver = timer{}

    session, err := clusterConfig.CreateSession()
    if err != nil {
        log.Fatal("Failed to connect to Azure Cosmos DB", err)
    }

    return session
}

我遇到以下错误：

unable to create session: control: unable to connect to initial hosts: Invalid Cosmos DB account or key

不知道这是什么问题。
