Ошибка подключения MongoDB с Go, ReplicaSetNoPrimary

Я пытаюсь подключиться к MongoDB из приложения Go, но получаю ошибку ReplicaSetNoPrimary.

Вот мой код подключения к MongoDB:

пример URI MongoDB:

mongodb+srv://user:[email protected]/?retryWrites=true&w=majority&appName=ntw

func SetupDB(uri string) *mongo.Client {
    log.Printf("Connecting to MongoDB")
    log.Printf("URI: %s", uri)
    ctx := context.TODO()
    client, err := mongo.Connect(ctx, options.Client().ApplyURI(uri))
    if err != nil {
        log.Fatalf("Failed to connect to MongoDB: %v", err)
    }

    defer func() {
        if err := client.Disconnect(ctx); err != nil {
            log.Fatalf("Failed to disconnect from MongoDB: %v", err)
        }
    }()

    if err := client.Ping(ctx, readpref.Primary()); err != nil {
        log.Fatalf("Failed to ping MongoDB: %v", err)
    }

    log.Printf("Connected to MongoDB")
    return client
}

Вот ошибка, которую я получаю:
