Comment (by hopetommola):

 Sorry for the delay. The weekend started with travel back from a
 conference and ended with moving two houses into one.

 * Yes, the siteurl is defined as https://blogs.hope.edu
 * No constants set for WP_SITEURL in wp-config.php
 * All values of wp_upload_dir() array are visible here:
 https://blogs.hope.edu/upload-test/

 Used:

 {{{
 <?php
 $uploads = wp_upload_dir();
 $uploads=implode("<br />",$uploads);
 echo $uploads;
 ?>
 }}}


 I have temporarily added the following to my child theme's functions.php
 file to force https:

 {{{
 add_filter( 'wp_calculate_image_srcset', function( $sources )
 {
     foreach( $sources as &$source )
     {
         if( isset( $source['url'] ) )
             $source['url'] = set_url_scheme( $source['url'], 'https' );
     }
     return $sources;

 }, PHP_INT_MAX );

 }}}
