Hi guys,

We are almost ready to deploy EO on our production environment, however, during our tests on our staging Azure deployment (cloud services) we are getting this error:

Time out expired before the page can be loaded.
at EO.Base.ThreadRunnerBase.c.a(Int32 A_0, Boolean& A_1)
at EO.Base.ThreadRunnerBase.Send(Action action, Int32 timeoutInMS)
at EO.Internal.o4.a(ady A_0, String A_1, String A_2, String A_3, Int32 A_4, Int32 A_5, String A_6, Boolean A_7)
at EO.Pdf.HtmlToPdfSession.a(ady A_0, String A_1, String A_2, Int32 A_3, Int32 A_4, String A_5, Boolean A_6)
at EO.Pdf.HtmlToPdf.ConvertUrl(String url, PdfDocument doc, HtmlToPdfOptions options)
at EO.Pdf.HtmlToPdf.ConvertUrl(String url, Stream stream, HtmlToPdfOptions options)

We also have an error handler that tries to return an empty pdf document, but it also fails with this error (from event viewer):

Exception information:
Exception type: HtmlToPdfException
Exception message: The request was canceled.

at EO.Pdf.HtmlToPdf.ConvertHtml(String html, PdfDocument doc, HtmlToPdfOptions options)
at EO.Pdf.HtmlToPdf.ConvertHtml(String html, Stream stream, HtmlToPdfOptions options)

I will continue working on this issue all day, but help would be appreciated here. The setup works fine on our dev environments.

Following your advice I stripped the original code to its simplest expression:


using (var memoryStream = new MemoryStream())
using (var streamWriter = new StreamWriter(memoryStream))
{
HtmlToPdf.ConvertHtml(string.Empty, streamWriter.BaseStream);

return memoryStream.ToArray();
}

This worked.

The original code looks like this:

HtmlToPdf.Options.OutputArea = new RectangleF(1.0f, 1.0f, 6.5f, 9.0f);
HtmlToPdf.Options.PageSize = new SizeF(8.5f, 11.0f);
HtmlToPdf.Options.MaxLoadWaitTime = 10000;
HtmlToPdf.Options.MinLoadWaitTime = 1000;
HtmlToPdf.Options.NoLink = true;
HtmlToPdf.Options.TriggerMode = HtmlToPdfTriggerMode.Dual;

foreach (var cookieKey in cookies.AllKeys)
{
var cookie = cookies.Get(cookieKey);
HtmlToPdf.Options.Cookies.Add(new Cookie(cookie.Name, cookie.Value, cookie.Path, cookie.Domain));
}

using (var memoryStream = new MemoryStream())
using (var streamWriter = new StreamWriter(memoryStream))
{
try
{
HtmlToPdf.ConvertUrl(url, streamWriter.BaseStream);
}
catch (Exception ex)
{
HtmlToPdf.Options.TriggerMode = HtmlToPdfTriggerMode.Auto;
HtmlToPdf.Options.MinLoadWaitTime = 1;
HtmlToPdf.ConvertHtml("<b>No Data!</b>", streamWriter.BaseStream);
}

return memoryStream.ToArray();
}

Let me know if you see anything weird. I'll investigate the DNS fix in the meantime.

I'm still trying to figure out how to do this in Azure. I also tried a few other things without success.

I can do that but I'll have to figure out a way to automate that. I'm still getting this:

The connection was reset.
at EO.Internal.o4.a(ady A_0, String A_1, String A_2, String A_3, Int32 A_4, Int32 A_5, String A_6, Boolean A_7)
at EO.Pdf.HtmlToPdfSession.a(ady A_0, String A_1, String A_2, Int32 A_3, Int32 A_4, String A_5, Boolean A_6)
at EO.Pdf.HtmlToPdf.ConvertUrl(String url, PdfDocument doc, HtmlToPdfOptions options)
at EO.Pdf.HtmlToPdf.ConvertUrl(String url, Stream stream, HtmlToPdfOptions options)

Is that related to the deadlocks?

I can't make it export a url from the local server. I can make it export external sites but not its own. Nothing helpful in the logs either. I'm out of ideas.

Had some time to try debugging this issue again. Sadly the host change is not enough. I still get the "The connection was reset" exception. I don't think ASPXToPDF or MVCToPDF is an option for me as I need to wait for some javascript to run before I render.

We went through the Event Viewer logs and found nothing, anywhere else I should be looking?
