Hi,

Please try to access exactly the same Url without "pdf=true" from within your server. For example, you can use Windows Remote Desktop to connect to your web server, then open any browser (Google Chrome preferred) on your web server and access the Url to see if all images/styles are rendered OK. If they do not render OK, then you may have a DNS problem, which is the most common cause for such problems. See here for more details:

If the problem still occurs, try to handle the ASPXToPDF's BeforeRender event and check HtmlToPdf.Options.BaseUrl value to see if that makes sense to you. If it is not correct (it can happen if you have something in the middle such as a load balancer), you can explicitly override it with code in your BeforeRender handler.

Thanks!

In case you do not have control over the server, you would just check the BaseUrl from your BeforeRender event handler and override the default value if needed. The key here is ASPXToPDF runs on your server, not on the client machine. So the same Url that is perfectly accessible from the client machine may not be accessible from within your web server. For example, while Url "http://www.yoursite.com/styles.css" is perfectly accessible from outside of your webserver, the same Url may not work from within your server because www.yoursite.com can point to an outside IP address that is not reachable from your web server.

Your goal is to fix this problem. The two options you have is:

1. Configure your server properly so that the same Url is accessible from within your server. For example, in the above case you can configure "www.yoursite.com" to point to "localhost" on your web server and make it reachable;
2. Override the default BaseUrl so that the converter would use an alternative Url to access the same resource. For example, the default base Url for the above case would be "http://www.yoursite.com", if you change it to "localhost", then the converter engine will look for "http://localhost/styles.css" instead, which can resolve the issue for you;

Note that here I gave you "localhost" is only for an example. Your host company may have different values so you may need to contact them to find out. The goal is to have the resources accessible from within your web server.
