Why 403 error on a specific file?

Question

PHP

Hello! The site worked for itself, transferred it from one godedi account to another, in 30 minutes the domain switched to another ns, it worked all day, everything is wonderful, and in the evening the error 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. and it was on this file - tinymce/plugins/contextmenu/plugin.min.js that he didn’t do anything, and he gave full and ordinary rights, and deleted the file and folder and uploaded it again, there is no access even crack ....
google is the only what could be - "dns has not been fully updated yet"...
- but how can this be? Everything is updated, but one file is missing?

Answer 1

If the file is on a Linux system, see access.
