Do not delete these files with the extension bundle when nginx + apache

Server
1

When you try to delete a downloaded or created files with the extension specified in the configuration nginx file - is a frontend, extension (jpg|jpeg|gif|png|svg|js|css|mp3|ogg|mpe?g|avi|zip|gz|bz2?|rar|swf|mp4|webm|ogg|ogv|mp3|m4v|m4a|flv) there is an error "error deleting file." or renaming "Could not rename file".
When direct hit on apache testhost.com:81 files are deleted or renamed without problems.
Also in the admin control panel, there is an error
Error PHP Function split () is deprecated at /home/user/data/www/testhost.com/lib/private/legacy/files.php#195

Expected behaviour
The files should be deleted or renamed when using reverse proxy nginx + apache

Actual behaviour
The files are not deleted or renamed with the extension specified in Nginx config

So no problems with the configuration and script do not work on the renaming and deleting when reverse proxy
