I had a different post in the media sharing and streaming section about the Subsonic guide, but I managed to get that figured out. Now I'm trying to follow this guide so that I can set up the cool reverse proxy rule, but I simply cannot seem to get it to work. Here is the error message I receive when I hit apply:
Obviously it seems to have something to do with permissions, but I'm not sure why. Any ideas would be great.
Also, does this guide work with something like Plex? That would be cool to have an add-on guide or something.
