Sample PDF View magazine?

when i clicked the link it throws the following error in the browser, eventhough the PDF exist in the same folder where viewer.html is. I'm not running this in webserver. I want to make it work it locally in my system. I don't need a web-server for local viewing. i have created a standalone HTML file which is created for my local PC use.....

PDF.js v1.0.1040 (build: 997096f)
Message: Unexpected server response (0) while retrieving PDF

How to create a standlone HTML file which opens the PDF as flipbook in my local browser

The problem is pdf.js, it uses fetch to get the pdf pages and the browsers don't allow it with the file:// protocol.
What some like this pdf to flipbook service does to run it locally is to launch a local web server to view the pdf flipbook.

Hello @erayakartuna,

What a great tool this is. I have got it working on my web server and now trying to integrate into my CMS. I am using Umbraco but cannot figure out why it is not working?

I am using HTTPS, would this make a difference?

Thanks

RESOLVED found a file that was needing referencing
