Pushing an Image to Mobile device with DuckDNS help

Any support would be greatly appreciated!

I am trying to send a notification to my iPhone which contains an image captured from my camera.
The problem i’m having is i don’t seem to be able to access any files remotely on my HA system.
I have DuckDNS setup and can access HA via the APP no problem both internally and externally
I can send the notification, which works fine, but when ever I try to access a file such as /config/www/snapshot.jpg I get a 401: Unauthorized

I’m new to HA and have limited experience so please dumb down any response.

Many Thanks
