expertPDF function GetPdfDocumentObjectFromHtmlString returns error "Conversion error: Webkit Navigation timeout"

Question

I am using expertpdf library to convert an html page in pdf and the function is giving error "WebKit Navigation timeout".

public void ConvertHTMLStringToPDF(string compHTML)
{
    var isIE8 = Request.Browser.Browser == "IE" && Request.Browser.MajorVersion <= 8;
    string htmlString = compHTML.Replace("valuesss", "value").Replace("scheckedss", "checked")
                                .Replace("<link href='includes/Print.css' />", "<style>\n" +
                                System.IO.File.ReadAllText(HttpContext.Current.Server.MapPath("includes/Print.css")).Replace("../images/", "images/") + "</style>");
