Captivate html 5 not loading

I hope this is the correct location for this post. I created a Captivate Classic project that includes images, text, and audio narration using the text to speech tool. I published it as html 5 and uploaded it to a publicly available Canvas site. If I am logged into Canvas, it plays fine. From outside it partially loads the first “slide” and then I receive the loading message and it never loads. That being said, I uploaded the healthcare template that comes with Captivate. I added some text to speech audio and it plays fine from the same Canvas site. It plays when logged in AND when I am not logged in to Canvas as it should since the Canvas site is public.   MP4s etc also play for individuals who are not logged into the public  Canvas site so it isn't a Canvas issue. The Healthcare template plays fine on my Windows  machine, Mac, and phone and even plays the text to speech but not the project I created without a template. Please advise.
