I am getting this error Ocassionally using your example code, happens when creating the PDF

Aspose.Pdf.License license = new Aspose.Pdf.License();
license.SetLicense(“Aspose.PDF.NET.lic”);

HtmlLoadOptions options = new HtmlLoadOptions(url)
{
PageInfo = { Width = 842, Height = 1191, IsLandscape = true }
};
Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(GetContentFromUrlAsStream(url), options);

private static Stream GetContentFromUrlAsStream(string url, ICredentials credentials = null)
{
using (var handler = new HttpClientHandler { Credentials = credentials })
using (var httpClient = new HttpClient(handler))
{
return httpClient.GetStreamAsync(url).GetAwaiter().GetResult();
}
}

Changed private static Stream GetContentFromUrlAsStream(string url, ICredentials credentials = null)
to not use GetStreamAsync(url).GetAwaiter().GetResult() and the problem went away.
apparently httpClient.GetStreamAsync(url).GetAwaiter().GetResult() doesn’t always wait for completion.

Below is the code that works

private static Stream GetContentFromUrlAsStream(string url, ICredentials credentials = null)
{
WebClient client = new WebClient();
byte[] bytes2 = client.DownloadData(url);
Stream stream = new MemoryStream(bytes2);
return stream;
}
