Comment (by kevinbkt10):

 In my case I use GD, the problem happens by uploading any JPG images, and
 absolutely no alternative sizes are generated, not even using plugins like
 regenerate thumbnail.

 I don't know how a picture could explain it. It has happened on all my
 sites within runcloud after I have upgraded to 5.3.1;

 A strange thing happened, today at 12:00 am the image I had uploaded a few
 days ago created the alternate size 375x175 that I set as a thumbnail
 size. But when I got home and realized this, my site was offiline on Wp-
 admin giving the following error 504, I had to restart Nginx and FPM to
 get online again.
