Hello,
I have an ASP.NET project in which I have a page containing some pictures. Everything has been working fine so far but today one of the users reported that they could not see any pictures on the PDF. They are actually not downloaded because they appear has a blue square with a question mark in but they are displayed correctly on the web page.
Everything is fine for the other customers and on my end too, dev server or prod server. I tried to access to the images the user requests for this page from a local browser on the server and I could reach them.
I would like to be able to debug further the method which generates the PDF. What would be the best way to do that?
Could it be something linked to the user's session or web browser? I am running out of ideas
Thank you
Grégory

Hi,
You will want to start from your web server log. When the converter needs to render an image, it first sends a request to your web server like a regular web browser does. If for some reason that Url is wrong or your web server didn't respond that Url properly, then you will get the blue question mark. By looking at your web server log you will be able to find out whether the Url is correct, or whether your server didn't server it correctly.
Thanks!

Thanks for this answer.
It seems that no events match the error and the time when the user tried to convert the page as a PDF. I am guessing the Url of the images were correct.
Would you have any other way?
Thank you

Hi, There are no other ways other than trial and error. If nothing shows up in your IIS logs, then the only possibility is for some reason the request didn't even reach your web server at all. Once common situation for this is DNS configuration error on your server, but that usually affects all users, unless that user uses a different domain name to access your site.
