I am trying to connect to the MongoDB server through a ssl certificate using c#. I am getting a System.TimeoutException (A timeout occurred after 30000ms selecting a server using the CompositeServerSelector).

What I have tried:

I started with connection via MongoClientSetting object. Here is the code:

MongoClientSettings settings = new MongoClientSettings();
settings.MaxConnectionLifeTime = new TimeSpan(12, 0, 0);

settings.UseSsl = true;
settings.VerifySslCertificate = false;
var cert = new X509Certificate2("mongoDBCAFile.cer");
settings.SslSettings = new SslSettings{
    ClientCertificates = new[] { cert }
};

settings.Servers = new[]{
    new MongoServerAddress("xyz1.intranet.companyname.com", 12345),
    new MongoServerAddress("xyz2.intranet.companyname.com", 12345)
};

settings.ReplicaSetName = "replicaName";

var cred = MongoCredential.CreateGssapiCredential("username@intranet.companyname.com").WithMechanismProperty("SERVICE_NAME", "servicename");
settings.Credential = cred;

var client = new MongoClient(settings);

var database = client.GetDatabase("DatabaseName");
var collection = database.GetCollection<BsonDocument>("CollectionName");

//This is the place of error
var count1 = collection.CountDocuments(new BsonDocument());

I tried playing around with ConnectTimeout, SocketTimeout, and wTimeOut but the error was same.

I also tried doing the same thing using the connection strinG but I wouldn't figure out how to create a connection string with these many parameters.
