Локальное подключение aws documentdb

Я могу успешно подключиться к кластеру AWS DocumentDB с помощью MongoDB Compass на своем локальном компьютере. Он использует SSH-соединение. Это работает.

Но я изо всех сил пытаюсь подключиться к базе данных из кода C# со своего локального компьютера.

var settings = MongoClientSettings.FromUrl(new MongoUrl("mongodb://master:password@abc-mongo.cluster-xyzxyz.eu-central-1.docdb.amazonaws.com:27017/database?ssl=false&readpreference=secondaryPreferred"));

var client = new MongoClient(settings);
var database = client.GetDatabase("database");
var databases = client.ListDatabases().ToList();

Я получаю ошибку:

A timeout occurred after 30000ms selecting a server using CompositeServerSelector{ Selectors = ReadPreferenceServerSelector{ ReadPreference = { Mode : SecondaryPreferred } }, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 }, OperationsCountServerSelector }.
