Comment (by luciantstoian):

 same problem here. I just tested uploading on another site, worked fine on
 wordpress 5.1.4, after upfating i get Unexpected response from the server.
 The file may have been uploaded successfully. Check in the Media Library
 or reload the page. if i try uploading files through admin and http error
 on front end.
 Has anyone figures this out?\\
