dotnet core Subscriber is not being triggered after Publishing

Question

I'm working on a Redis(StackExchange.Redis) PUBSUB system in Dotnet core and everything works normally until after I publish to my channel. The subscriber simply won't ever be triggered.

Here is my code:

program.cs

public static void Main(string[] args)
        {
            _ = RunConsumer();
            BuildWebHost(args).Run();
        }

        private static async Task RunConsumer()
        {
            LogWriter logger = new LogWriter();
            IEnvironment envProvider = new EnvironmentProvider();

            try
            {
                ICache cache = new Cache(envProvider);
                IDataRepository dataRepo = new DatabaseRepository();
                PubBusiness publisher = new PubBusiness();
                await publisher.ImportData();
            }
            catch (Exception ex)
            {
                await logger.WriteLogErrorAsync($"Exception occurred", ex);
                Environment.Exit(-1);
            }
        }

Publisher

// ... code that creates my key

// add my data to a batch and save it to redis
batchTasks.Add(batch.ListRightPushAsync("jobs", key));
batch.Execute();
Task.WaitAll(batchTasks.ToArray());

// publishing
ISubscriber sub = _connection.GetSubscriber();
await sub.PublishAsync("uploaded", key);

Subscriber

var db = _connection.GetDatabase();
ISubscriber sub = _connection.GetSubscriber();

// it will never pass here
            await sub.SubscribeAsync("uploaded", async (channel, value) =>
            {
                var key = (await db.ListLeftPopAsync("jobs")).ToString();
               // do my stuff here
            });

Messaging disabled by default, follow the link for details BUT if short, just enter this command to redis cli to enable all:

CONFIG SET notify-keyspace-events KEA
