在VPS上执行某些命令后，带有托管API的控制台应用只是停止

如何解决在VPS上执行某些命令后，带有托管API的控制台应用只是停止

我有一个使用此命令的discord机器人。

[Command("synopses",RunMode = RunMode.Async)]
[Summary("Shows current synopses.")]
public async Task Synopses(string username)
{
    var warning = await ReplyAsync($"{Context.User.Mention} I am querying the Tracker,this may take a moment.");
    var synopses = await _trackerService.GetUserSynopses(username);
    var pager = BuildSynopsesPager(synopses);
    await warning.DeleteAsync();
    await PagedReplyAsync(pager,new ReactionList());
}

_trackerService.GetUserSynopses(username);是一项非常长的任务，大约需要10秒钟。

public async Task<List<Synopsis>> GetUserSynopses(string username)
{
    var synopses = new List<Synopsis>();
 
    // This request to the Google Sheets API is the bulk of the time.
    // It gets about 4k rows.
    var tracker = await GetTrackerAsync();

    foreach (var sheet in tracker.Sheets)
    {
        var data = sheet.Data;
        
        var writes = data
            .Select(x => x.RowData)
            .First()
            .Where(x => x.Values.Count >= 11)
            .Where(x => x.Values[3].FormattedValue == username);
        
        static bool ParseFinal(string text)
        {
            return text switch
            {
                "Yes" => true,_ => false
            };
        }
    
        var result = writes
            .Select(write => write.Values)
            .Select(cells => new Synopsis
            {
                DateClaimed = cells[0].FormattedValue,SeriesTitle = cells[1].FormattedValue,SeriesHyperlink = cells[1].Hyperlink ?? "No Hyperlink",ClaimType = Enum.Parse<ClaimType>(cells[2].FormattedValue),Claimant = cells[3].FormattedValue,Document = cells[4].Hyperlink ?? "No Hyperlink",Final = ParseFinal(cells[5].FormattedValue)
            });
    
        synopses.AddRange(result);
    }
    
    return synopses;
}

public async Task<Spreadsheet> GetTrackerAsync()
{
    await using var stream = new FileStream("credentials.json",FileMode.Open,FileAccess.Read);

    var credential = GoogleCredential
        .FromStream(stream)
        .CreateScoped();

    var sheetsService = new SheetsService(new BaseClientService.Initializer
    {
        HttpClientinitializer = credential,ApplicationName = "Hiromi"
    });
    
    const string spreadsheetId = "1wbIqigHMGFWZebum8mQjSL5eQzSAXuWZS-8ewbfX4PI";

    var request = sheetsService
        .Spreadsheets
        .Get(spreadsheetId);

    request.IncludeGridData = true;
    request.Ranges = new[] {"'Synopses In Progress'!A3:K","'Archive'!A2:L"};

    return await request.ExecuteAsync();
}

因此，当我的应用程序从IDE在本地运行时运行此命令时，无论执行多少次，它都可以正常工作。但是，当我的应用程序从VPS运行时，它第一次运行，但是第二次执行var warning = await ReplyAsync($"{Context.User.Mention} I am querying the Tracker,this may take a moment.");，然后挂起一会儿，然后立即停止。

如您所见

该过程结束了，但不是因为我终止了它；几秒钟后它自动终止。

知道什么问题吗？
