Seagate Personal Cloud can't find Plex

I have bought a Seagate Personal Cloud 2 bay and I managed to install and run Plex on it from the beginning. It was quite a hard time to configure it, but I managed to do it by installing it manually.
The setup was stable and running for about two weeks - and I was happy!

Unfortunately it stopped working a couple of days ago. I have a theory that it has to do with the new firmware on the Personal Cloud. My NAS is now - finally - up and running again, but Plex isn’t. I have tried to install and installed both the native Plex and latest Plex software from Plex.tv, but nothing works. When I hit the Plex icon a new webpage opens, and nothing happens. Its just blank for about forever, and nothing happens. I have tried both Safari, Explore and Chrome. Nothing works. I have tried to reboot the NAS several times. Nothing happens.

Can anyone help?? Seagate won’t help - they just refers to Plex. And Plex can’t be contacted, SO now its up to you guys! Please help…

I had the same issue and I updated firmware to 4.3.11.5 and manually install the newest version of Plex com.plex.plexmediaserver-1.3.4.3285 (download from Plex side for Seagate). This helped me but during last week when plex didn’t working I created new account and also manipulate time zone of Personal Cloud. (some user recommend this).

I do not know what fixed this, but now is working properly.

@LukaszS - good to hear somebody finds a solution from time to time.

As for my own case, I fixed it by changing back to the original Ethernet cable. I was using a longer, and actually better quality cable, but somehow it couldn’t work. So after a switch of cables I just run Plex ones again. I also removed my old server and created a new one. And now it’s working.

What if I’m not running ethernet? My Rokus are wifi, and so is the drive?
