Question

A timeout occurred after 30000ms selecting a server

using CompositeServerSelector
{
  Selectors = MongoDB.Driver.MongoClient+AreSessionsSupportedServerSelector,
  LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 }

    ClusterId : "1", 
    ConnectionMode : "ReplicaSet", 
    Type : "ReplicaSet", 
    State : "Disconnected", 
    Servers : [
    { 
        ServerId: "{ ClusterId : 1, EndPoint : "Unspecified/mdr-non-prod-tst-shard-00-00-4rmha.azure.mongodb.net:27017" }",
        EndPoint: "Unspecified/mdr-non-prod-tst-shard-00-00-4rmha.azure.mongodb.net:27017", 
        State: "Disconnected", Type: "Unknown", LastUpdateTimestamp: "2020-03-30T14:09:08.2853263Z" },
        { 
            ServerId: "{ ClusterId : 1, EndPoint : "Unspecified/mdr-non-prod-tst-shard-00-01-4rmha.azure.mongodb.net:27017" }", 
            EndPoint: "Unspecified/mdr-non-prod-tst-shard-00-01-4rmha.azure.mongodb.net:27017", 
            State: "Disconnected", 
            Type: "Unknown", 
            LastUpdateTimestamp: "2020-03-30T14:09:08.2963257Z"

Have you tried adding ?connect=replicaSet after your connection string :

new MongoClient("mongodb://username:password@ds011111.mongolab.com:11111/db-name?connect=replicaSet")

Basically the default is to connect to a replica set member. But MongoLab's Single-Node settings are actually a single node replica set and this causes us to not trust it. Appending ?connect=replicaSet to your connection string will force the driver to move into replica set mode and all will work.

You can refer to this case with similar issue for details.
