I did a refresh of my LG TV 3 days ago. Sold the old LG 47" 3D LED TV and bought new 55" LG Super UltraHD TV with WebOS. I believe, the biggest con of this new TV is WebOS. Its totally frustrating. Sorry for WebOS fans.
It isn't that smart and functional they way it looks. The problem I having since 3 days and being a network engineer, I am unable to solve a network issue myself which is even more frustrating for me.
Ok, let me explain the issue. The TV when installed was connected to LAN cable to my router which has direct internet connection. The TV works and none of the apps were working. Basically TV wasn't able to connect to internet via apps. If i open web browser, it was working fine with all webpages showing correctly.
I'll skip the part of contacting LG support which was useless. All troubleshooting steps like resetting, formatting, changing time zone, location, region was done but no luck. Finally I connected the TV via mobile hotspot and it just worked which gave me the clue that some ports are being blocked by my ISP or router.
My internet setup is this way. Internet cable from ISP -> ISP Modem (can do NAT and work as router) - WiFi Router (NAT, DHCP, etc) -> all LAN clients. I put my LG TV in DMZ, opened all ports, etc but no luck. Then I converted my ISP modem as router and connected the LG TV directly to it and it started working..!!!
My WiFi Router is TP-Link Archer C7 and I was using stock firmware. Thought it was creating issues and I installed DD-WRT, Open-WRT but no luck at all. The apps which were installed in TV when TV was connected directly to modem are still working fine. Youtube, Plex, Netflix, etc all are working but when I open LG Content Store, it just refuses to load.
I am not sure what wrong my TP-Link router is doing. There is something wrong with the LG TV content store. If it requires to open ports, then I would like to know which ones.
Sorry for the long port, may be my frustration of 3 days with no luck.!!

Question
Mr Darcy
Hi,
I have an OLED65C9PLA. Was fine when I went on holiday came home and Netflix and Prime wasnt working.
My current situation is I can use the TV web browser and search for and open web pages no problem at all, but if I press the Netflix or Prime button I get the LG content loading screen (the redish picture with a tv on it) then after a few seconds a black screen with try again. Error code -7 or sometimes a -34? cant remember. Network is fine both Wifi and cable. I use cable for the TV but have removed and tried with Wifi. Same results. If I select the LG content App it does the same loading screen then error. Everything else seems fine, just when ever the content apps are needed crash.
I have looked into many things, removing the plug from the wall (left for over 30min), Some hard reset thing where you press and hold the power button for 20 seconds, Factory reset. From what I can see I have the latest LG software 5.20.15. As I said all was good when I left, nothing changed then didnt work. Any help or ideas would be greatly appreciated.
Thanks
