   Cannot Access File, I cannot find a common cause. Sometimes it works on all pages,
   sometimes it fails on some, sometimes it works on none. I tried different browsers
   and I also tried clearing my cache.

   pages is where the pdf is displayed:

 * Hi,
 * I had a look at the page and I found a redirection issue.
 * The site serves non www and www both. The pdf files are expected at www variant
   in both cases.
 * [https://britspa.co.uk/annual-scientific-meeting/](https://britspa.co.uk/annual-scientific-meeting/)
   Here it wont work you get a CORS issue.
 * [https://www.britspa.co.uk/annual-scientific-meeting/](https://www.britspa.co.uk/annual-scientific-meeting/)
   here it works.
 * Make sure you are redirecting non www to www variant.
 * Best Regards,
 * Deepak
