ASP.Net Core BackgroundService is cancelled without reason

I developed a BackgroundService, at the beginning it works Ok. But later at 20 minutes this is cancelled for some reason that I don't know. For this case in particular, the "job" should be infinite and never finish. Please, could you give some idea ? I'll appreciate it

public class CheckItemsService : BackgroundService
{
    private IConfiguration Configuration { get; }

    public CheckItemsService(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        stoppingToken.Register(() => Log.Information("Job is stopping"));

        while (!stoppingToken.IsCancellationRequested)
        {
            await UpdateItems();

            await Task.Delay(1000 * 60, stoppingToken);
        }
    }

    private async Task UpdateItems()
    {
        var optionsBuilder = new DbContextOptionsBuilder<WalletContext>();
        optionsBuilder.UseSqlServer(Configuration.GetSection("ConnectionStrings:Default").Value);
        DbContext _context = new DbContext(optionsBuilder.Options);

        var items = await _context.EntityX.ToListAsync();

        foreach (var item in items)
        {
            item.ModificationDate = DateTime.Now;
        }

        try
        {
            await _context.SaveChangesAsync();
        }
        catch (DbUpdateException dbEx)
        {
            Log.Information(dbEx.Message);
        }
    }
}

@Scott Chamberlain Thanks man, in base on your comment you gave me the idea of searching why the host was shutting down, so I figured out that IIS has a default configuration for "inactivity" in every site for 20 minutes. I changed this and it's working perfectly. @Vidmantas Blazevicius Thanks so much man, indeed this was the reason of my problem. Appreciate it for your help.
