Hi all,
A recent update to our security certificates on plex.tv and Plex Media Server installs had the unfortunate side-effect of making the PS3 app unable to communicate with plex.tv and servers who had their certificates updated. Unfortunately reverting these changes is not a feasible option, as it would compromise the security of our other devices and services.
Despite the PS3 app being unsupported for many years now, we are looking into other possible solutions but truthfully it is unlikely the PS3 app will become functional again. We are unable to update the PS3 app and it is unlikely that Sony will update the system to support modern certificates. While we did inform users that the app was no longer supported, we should have perhaps done a better job explaining that this was situation was a possibility and for that I apologize.
