Aspose.pdf Error "The remote server returned an error: (404) Not Found."


I’m using Aspose.pdf.dll in C# (version 4.6)
And I get this error almost every time (sometimes it is working).
It is failing at this statement: pdf1.Save(pdfStream);

Error is:
"The remote server returned an error: (404) Not Found."

My code is this:

public Stream Convert(Stream xmlStream, Generator generator)
using (var temp = new MemoryStream())
CopyStream(xmlStream, temp);

switch (generator)
case Generator.Aspose:
string licenseLocation = ConfigurationManager.AppSettings[“AsposeLicenseFileLocation”];
if (!string.IsNullOrEmpty(licenseLocation))
new License().SetLicense(licenseLocation);
var pdfStream = new MemoryStream();
Pdf pdf1 = new Pdf();
pdf1.BindXML(temp, null);
pdfStream.Seek(0, SeekOrigin.Begin);
return pdfStream;
temp.Seek(0, SeekOrigin.Begin);
return RetrieveFromStream(temp);

Do you have any idea why it is failing?

Hi Mihai,

I have tested the scenario using Aspose.Pdf for .NET 9.1.0 and I am unable to notice any exception/error. However, I have observed that resultant PDF is 0KB. For
the sake of correction, I have logged it in our issue tracking system as PDFNEWNET-36765. We will
investigate this issue in details and will keep you updated on the status of a

We apologize for your inconvenience.

Hi Nayyer,

I found the issue. In my xml, one image link was pointing to a missing image file. (http://localhost/Images/PDF/AlphabetPoland.jpg)

This is why I got 404 not found.

So no need to investigate it.

Thanks and Regards,


Hi Mihai,

We are glad to hear that your problem is resolved. However, during my earlier attempt, I was unable to convert the XML to PDF format. Can you please confirm the current version which you are using ?

PS, as per my observations from your first post, are you using 4.6.0 ?


Yes, my version is 4.6.
Do you see any additional problems reg. the code or the xml structure?
What should I do to improve the code?


Hi Mihai,

Thanks for sharing the details.

In one of your earlier replies, you have stated that once you have specified the correct URL for image object inside XML, the problem is resolved. However during my testing with latest release, the resultant PDF being generated is 0KB even I have updated the image URL’s to correct path. The problem has already been logged in our issue tracking system and as soon as we have some further updates, we will let you know.


Ok, this may explain our errors on test/uat and production which occur from time to time…
Please let me know about your updates.

Thanks and Regards,

Hi Mihai,

The development team will investigate and try resolving this issue based on its schedule and as soon as we have some further updates, we will let you know.
