 In an update/continuation of abandoned (not by me) ticket #43310, I need
 to bring this issue back to the forefront. After one of my Co-workers and
 I did some additional testing, we have identified the "HTTP Error" is a
 result of some PHP versions not being able to generate thumbnails from the
 first page of a PDF (a change that was introduced within the 4.7 release).

 The issue is that there is no fall-back option when WordPress is unable to
 generate thumbnails.

 We loaded the [https://wordpress.org/plugins/disable-pdf-thumbnails/
 Disable PDF Thumbnails] plugin on the sites that were returning that "HTTP
 Error" and were able to successfully upload PDFs without any problems.

 Wordpress should auto-detect PDF image thumbnail creation "http errors"
 and switch to the following fallback upon failure:
 {{{
 function makeworthy_disable_pdf_thumbnails() {
         $fallbacksizes = array();
         return $fallbacksizes;
 }
 add_filter('fallback_intermediate_image_sizes',
 'makeworthy_disable_pdf_thumbnails');
 }}}

 The other thread (linked above) has some of our system information
 available, however, I can provide updated details (or FTP/WP-Admin access
 to the dev that fixes this), as needed.

 Hi there,

 Sorry you still haven't got a reply on #43310, but it's still open, so
 let's continue the discussion there. No need to create a new ticket for
 the same issue.
