New to Plex & can't get media working hosted on PC to shield

Server Version#:
Player Version#:
Morning,
I’m new to plex and think it’s great. I’ve got my media based on my PC, which works fine. I can stream to my ipad over the same network, but trying to access the content on my Shield in the bedroom and it doesn’t work. I can see the content, I’m logged in to the server, but when I try to play it says ‘An error occured while attempting to play this video, please try restarting both the plex media server and this app’…which I’ve tried many times, and still nothing. I though it may be the firewall on my pc (norton), but works fine with my Ipad, so can’t be blocking traffic of the server out bound.
Does anyone have any ideas?
TIA

Danny

Did you update the Plex app on the Shield? It comes pre-installed on the Shield but it’s an old version and likely doesn’t work well any more.

Wow, great stuff. that works
Thanks so much, can’t believe I didn’t think of it
