Couchbase.Exceptions.UnAmbigousTimeoutException с использованием Python SDK

Я получаю couchbase.exceptions.UnAmbiguousTimeoutException каждый раз, когда пытаюсь подключиться к своему кластеру Couchbase с помощью Python SDK. С тем же именем и конфигурацией у меня нет проблем с подключением через .NET SDK.

Это мой код Python:

class CouchbaseBase:
    def __init__(self, endpoint, username, password, bucket_name):

        logging.basicConfig(filename='example.log',
                            filemode='w',
                            level=logging.DEBUG,
                            format='%(levelname)s::%(asctime)s::%(message)s',
                            datefmt='%Y-%m-%d %H:%M:%S')
        logger = logging.getLogger()
        couchbase.configure_logging(logger.name, level=logger.level)

        # Connect options - authentication
        auth = PasswordAuthenticator(username, password)
        timeout_opts = ClusterTimeoutOptions(connect_timeout=timedelta(seconds=60),
                                             kv_timeout=timedelta(seconds=60))

        # get a reference to our cluster
        options = ClusterOptions(auth,
                                 timeout_options=timeout_opts,
                                 disable_mozilla_ca_certificates=True,
                                 enable_dns_srv=False,
                                 tls_verify=None)
        cluster = Cluster.connect(f"couchbase://{endpoint}", options)

        # Wait until the cluster is ready for use.
        cluster.wait_until_ready(timedelta(seconds=5))

Единственное отличие, которое я вижу в своей конфигурации .NET, заключается в том, что есть некоторые параметры для HttpIgnoreRemoteCertificateMismatch и KvIgnoreRemoteCertificateNameMismatch, которые в моем случае я установил на true, но не могу найти ни одного для python sdk.

.NET эквивалентный код, который работает без проблем:

_clusterOptions = new ClusterOptions();
config.GetCouchbaseClientDefinition().Bind(_clusterOptions);

_clusterOptions.HttpCertificateCallbackValidation += new RemoteCertificateValidationCallback((object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors) =>
{
    return true;
});
_clusterOptions.KvCertificateCallbackValidation += new RemoteCertificateValidationCallback((object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors) =>
{
    return true;
});

_clusterOptions.NetworkResolution = "external";
_clusterOptions.EnableDnsSrvResolution = false;

_clusterOptions.WithSerializer(new CouchbaseSerializer());
_clusterOptions.AddLinq();
_clusterOptions.KvTimeout = TimeSpan.FromSeconds(10);

_cluster = Cluster.ConnectAsync(_clusterOptions).Result;
