Hi what you need to do is very simple.
Just turn your LG TV of at the power source (plug).
Wait 1x minute.
Reconnect the plug/ flicking switch to on.
Turn TV on from remote control or TV button.
Try reconnect to Now TV app it should be working now.
Have you tried either of the 2 options.
1. Delete and reinstall the app?
2. Set your TV back to factory settings?
This option often is successful in clearing bugs in the software.
Worst case you'll need to report it as a fault with Now TV
I've had this problem on a 2015 LG TV and I've just resolved it myself.
Go into the apps on your LG TV and delete the nowtv app
Go into the LG content store and search for now tv
Download the updated now tv app again
Launch the app and you should be back in business, well it worked for me so hopefully it will for you as well
Says Unknown Page Error...Something's Not Right...
Check connection and try again.....which is weird, was working fine last night (binge watching MacGyver) and today, it's not happenin'. I have a webOS LG tv, and I know the other version is no longer supported, so I'm lost 😕
When i had an LG TV I found that the Now TV app was very unreliable.
A few times setting the TV back to factory settings often is best for squashing bugs. Have you tried setting it back to factory settings?
Apart from buffering now and again I didn’t really have trouble with the app. The stick, however, is a nightmare.
I did reset. Made the other apps (prime, Disney) even slower. After I reset, it wouldn’t even load. Just gave me the Gangs picture and a QR code...
