File upload error - unable to create a temporary file in Unknown on line 0

I keep getting this error everytime i try to upload an image using laravel

unable to create a temporary file in Unknown on line 0

in my app the /storage directory has these permissions

drwxrwxrwx  5 www-data www-data    4096 Oct 25 10:04 storage

and the tmp directory has these permissions

drwxrwxrwx   3 root root  4096 Jul 13 13:48 tmp

Any suggestions on how i could solve this ?
