Samsung Plex App cannot find myplex

Hi Everybody,

My Plex App on my TV has stopped working. It says it cannot access the network or that the myplex server is down. I have checked both:

• My Netflix app is working correctly.
• I can access plex from my tablet and telephone.

I have all latest version istalled and I tried reinstalling the plex app, but it still tells me the myplex server is down. The TV is a UE40ES7000 with software version T-ECPDEUC-2011.1,BT - S/I/G

Does any of you have any suggestions?

Thanks,

Marc
