I used to be able to do this, on a previous version of Plex Media Server, but now that I re-installed PMS the “right” way (i.e. so service plexmediaserver start works) this has STOPPED working.
The attached image shows a user who can browse to root to find their media folder. Mine, in the FreeBSD jail, lives at /media which is exactly where I want it.
However, when I want to add a folder to a library, I see this:
No option to browse to /media
Now, /media IS there; I can tell when I’m ssh’d to the server. And it IS accessible to the Plex user. In fact, if I hard type /media in the textbox at the top of the “add folder” dialog it finds my movies and adds them no problem.
But (for various reasons) I need that button to browse me to / back.
