EVO HTML to PDF Client for UWP Demo issue

Question

I'm experiencing problem running EVO HTML to PDF Client for UWP Demo.

I made an installation package of the demo application and deployed it to a separate computer. EvoHtmlToPdfService is installed and working. But when I try to convert HTML to PDF, I get an error (see screenshot). When I run the application on another computer from a Visual Studio environment, everything is fine.

I suspect it's the firewall, which blocks access to 127.0.0.1:40001. But I have no idea how to configure the firewall to allow these calls. Or is there something else going on here?

Answer 1

Uwp applications are sandboxed, which can’t access the localhost directly. So could you please try to enable loopback for this uwp app?
