 Worked with hosting provider and they confirmed permissions are correct as
 well.

 It is not about WordPress but encountering the "chmod: Operation not
 permitted" error in Linux typically means you lack the necessary
 permissions. By using sudo to execute commands with superuser privileges
 or changing the file ownership to your user, you can resolve this issue
 and successfully modify file permissions.
