Hmm, are you still facing this issue? The message you're referring to should only show if you've put something in the Subscriber redirect field, which is currently not the case. (Maybe you changed that recently?)
This field is only required if you've decided to continue hosting future episodes on a different host than SoundCloud. (This way, your listeners will still be able to get your older episodes).
If you do so, it is expected behavior when you're loading a redirected feed in a browser, it’s a security measure - the redirect will go through fine in a podcast app though.
Hope this helps!
