When exporting data from EPi we get a "website not available" and the actual downloadable file as 0 bytes (sorry, the image is in swedish).

The site is quite large with a lot of content and related images etc.

I've tried every setting I can think of - this issue doesn't seem to exist locally when running F5.

How ever we need it on the production servers in Azure. I'm guessing there is a timeout issue somewhere?

private const long MaxBodySize = long.MaxValue;

// If using Kestrel:
services.Configure<KestrelServerOptions>(options =>
{
	options.Limits.MaxRequestBodySize = maxBodySize;
	options.Limits.KeepAliveTimeout = TimeSpan.FromMinutes(60);
	options.Limits.RequestHeadersTimeout = TimeSpan.FromMinutes(60);
});

// If using IIS:
services.Configure<IISServerOptions>(options =>
{
	options.MaxRequestBodyBufferSize = maxBodySize;
	options.MaxRequestBodySize = maxBodySize;
});

services.Configure<FormOptions>(options =>
{
	options.ValueLengthLimit = maxBodySize; // Limit on individual form values
	options.MultipartBodyLengthLimit = maxBodySize; // Limit on form body size
	options.MultipartHeadersLengthLimit = maxBodySize; // Limit on form header size
});

services.Configure<UploadOptions>(options => options.FileSizeLimit = maxBodySize);

// app
app.UseWhen(context => context.Request.IsEPiUiPath(), builder =>
{
	var maxSizeFeature = builder.ServerFeatures.Get<IHttpMaxRequestBodySizeFeature>();
	if (maxSizeFeature is null || maxSizeFeature.IsReadOnly)
	{
		return;
	}
	maxSizeFeature.MaxRequestBodySize = maxBodySize;
});

// Web.config
<aspNetCore processPath="dotnet" arguments=".\xxx.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" requestTimeout="02:00:00" />
