Worked for me.  Thank you  Solution Fixed.

AIP-701

Worked like a champ after deactivation and logging back in but all I needed to do was go into settings and choose deactivate instead of the arrows combo, thanks!

Also worked for my netgear neotv...thanks

It worked woohoo!!

Thanks so much, worked perfectly with my D link.

 I don't have an LG Smart TV, but I do have an LG Blu ray player with the Netflix app.  I did not have to do all the up down left right button pushing described in other solutions.  I simply opened the Netflix app, went to Settings (which brought a screen with info on my LG Blu ray player and contained a Deactivate button), selected Deactivate, and then went through the process of logging back into Netflix with my email and password.  This worked for me. 

Worked on my LG Blueray 3D player.

Does anyone know exactly WHY this happens? Seems to happen literally outta nowhere, with no changes made to the device Netflix is running on?

Didn't work on XBOX 360 in Australia. It just keeps happening
