I'm using Winnovative PDF Converter to generate PDF files from HTML (URL)

When triggering a button on a HTTP web page, to generate a PDF from a HTTP URL, this works fine.

However when triggering a button on a HTTPS web page, to generate a PDF from a HTTP URL, I get the error:

Could not render the url. Could not get image from url.Navigation timeout..

Why is this happening and how can I prevent it?

Please Note: I'm not getting an error when generating a PDF of a HTTPS page, I'm getting an error when making a web request from a HTTPS page to generate a PDF

  • I successfully created a PDF version of `https://www.google.com` from the live demo module they had given in their homepage. Maybe there is a certificate trust issue? –  Oct 06 '11 at 12:38
  • The Winnovative website isn't in SSL mode. I think you may have misunderstood my question. Generating a PDF from a HTTPS page works fine, its making a request from a HTTPS page to generate a PDF which returns the error. Sorry if I haven't made this clear – Curtis Oct 06 '11 at 13:19
  • Just some ideas -- Does the same thing happen with different browsers? Also does the page that you are generating have any cache directives that make it "private" or "no-cache" or expires immediately? There are sometimes issues in IE, with files like PDF/Excel/SWF that are not to be cached over SSL. Also if you're going from HTTPS to HTTP perhaps there is a "this page has secure and insecure content" issue. Don't know how the winnovative tool works but does the same request work HTTPS->HTTPS? It is just HTTPS->HTTP that errors out? – mikey Oct 06 '11 at 13:52
  • I had the same issue and I suspected the ssl as well. But it did work on another server with same ssl certificate. The only difference was the IE versions, since Winnovative uses IE, I uninstalled IE9 on the server which it was faulty and IT WORKED with IE8. – Oracle Apr 23 '13 at 09:56
