cant write auth file

[loady]

I am running deluge in an unraid enviroment as a docker and have not had issue with this before, i cant open the auth file to edit it, i am using notepad++ and say it cant be opened, no explanation, i have tried copying file to desktop and opening it but still no joy, all the other files within the deluge directory open fine, i tried deleting it and noticed it created a new one but still i cant open it to edit it..what gives ?
