Basically what the title said.. plex for Mac, just updated it as of Oct 22 2015, everything works from a port and remote access perspective but when my iPad or iPhone clients (or windows 8) try to access from outside the home network (which works mostly well) the remote play starts, allows me to select media, and lets me start playback. Then the circle spins, the first frame of the video shows up, and then nothing. Playback never actually starts, just the same single frame of the video forever.
Any ideas?
