System.Net.Sockets.SocketException

Question

Hi Team

 

I am trying to readmessage2device, each time want to readmessage2device, i often get this websocket exception.

 

This method it does the following for running;

private static async Task Main(string[] args)
{
Console.WriteLine("IoT Hub App - Read device to cloud messages.");
var connectionString = new EventHubsConnectionStringBuilder(new Uri(s_eventHubsCompatibleEndpoint), s_eventHubsCompatiblePath, s_iotHubSasKeyName, s_iotHubSasKey);
s_eventHubClient = EventHubClient.CreateFromConnectionString(connectionString.ToString());
var runtimeInfo = await s_eventHubClient.GetRuntimeInformationAsync();
var d2Partitions = runtimeInfo.PartitionIds;
CancellationTokenSource cts = new CancellationTokenSource();
Console.CancelKeyPress += (s, e) =>
{
e.Cancel = true;
cts.Cancel();
Console.WriteLine("Exiting...");
};
var tasks = new List<Task>();
foreach(string partition in d2Partitions)
{
tasks.Add(ReceiveMessagesFromDeviceAsync(partition, cts.Token));
}
Task.WaitAll(tasks.ToArray());
}
}
}

What could be the reason for this? Firewall issue or network, cant seem to understand where its getting it from.
