Странный сбой с ответами HTTP 502 в приложении ASP.NET Core ⇐ C#

[Anonymous]

У меня есть сайт, и иногда я получаю простой ответ HTTP 502, открывая любую страницу, это случается редко. Не могу найти, что это может быть .. < /p>
Иметь журналы ниже, я искал некоторую информацию.Startup.Configure:
app.UseForwardedHeaders();

lifetime.ApplicationStarted.Register(() =>
{
});
lifetime.ApplicationStopped.Register(() =>
{
});

// Error handler
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
}
else
{
app.UseExceptionHandler("/error");
}

var config = GetConfigValues();
app.UseStatusCodePagesWithReExecute("/error", "?statusCode={0}");

app.UseHsts();
app.UseHttpsRedirection();

app.UseResponseCaching();
var cachePeriod = env.IsDevelopment() ? "600" : "15000000";

app.UseDefaultFiles();

StaticFileOptions options = new StaticFileOptions {
ContentTypeProvider = new FileExtensionContentTypeProvider(),
OnPrepareResponse = x =>
{
// Requires the following import:
// using Microsoft.AspNetCore.Http;
x.Context.Response.Headers.Append("Cache-Control", $"public, max-age={cachePeriod}");
}
};

app.UseStaticFiles(options);

app.UseCookiePolicy();
app.UseAuthentication();

app.UseSession();

app.UseSiteConfiguration(config); // SITE SETTINGS
AddRoutesAndMvc(app); // addmvc + routes

app.UseRequestLocalization();
app.UseKendo(env);
