Creating Buckets through Management API causing Socket Exception

.NET SDK
1

I am trying to programmatically create buckets using IClusterManager.CreateBucket and am getting a SocketException.ConnectionAborted 10053 error consistantly when attempting to create the second bucket on localhost. The code I am using to reproduce is

using System;
using System.Collections.Generic;

using Couchbase;
using Couchbase.Configuration.Client;

namespace CouchbaseManagementReset
{
    class Program
    {
        static void Main(string[] args)
        {
            var config = new ClientConfiguration
            {
                Servers = new List<Uri> { new Uri("http://localhost:8091") }
            };

            using (var cluster = new Cluster(config))
            {
                var manager = cluster.CreateManager("Administrator", "password");

                for (var i = 0; i < 2; i++)
                {
                    var result = manager.CreateBucket($"bucket{i}");

                    if (!result.Success)
                    {
                        Console.WriteLine($"bucket{i} failed - {result.Message}");
                    }
                }
            }
        }
    }
}

and the resulting logfile has the error

Couchbase.Management.ClusterManager Error System.Net.WebException: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. ---> System.IO.IOException: Unable to read data from the transport connection: An established connection was aborted by the software in your host machine. ---> System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine

I’m running Couchbase Server 3.1.1-1807 Enterprise Edition, and am using Couchbase.NetClient 2.2.1.0 on Windows 7 Professional. Oddly enough, having somebody else remotely connect to my Couchbase Server instance and run the same code does not produce the same error, seems restricted to localhost.

Any ideas or additional information I could provide?
