This is a strange issue. Ever since I installed Drupal 8 (currently 8.6.3) on a managed HostPapa host, I cannot get thumbnails to display for specific file extensions. When I watch the browser dev console, it never creates them under styles. I’ve already cleared the cache from Configuration and rebuilt permissions/checked permissions. I’m running a multi-site setup.
What’s really bizarre is that certain case sensitive extensions work.
Thumbnails that don’t work: .jpg .png
Thumbnails that work: .JPG, .JPEG, .jpeg, .PNG
If I rename the exact same file with a ‘good’ extension, the thumbnail gets created and everything works perfectly. I’m thinking there is some htaccess file somewhere or hardcoded item that blocks jpg/png from being created in styles. I was forced to use the Softaculous Apps Installer which I believe is modifying the drupal install in some strange way and creating this issue.

Update: just to be clear, the issue occurs in all browsers. And if I actually create the file in the styles folder manually, it still doesn’t see it and gives the same error.
