Resolved Question

LG Content Store is not working

Jan 25, 2019 1:45PM PST

My TV is LG Smart TV 43LJ550V with firmware updated; and it is connected to Internet via Wi-Fi (Modem/Router: Linksys X3500 and Range Extender: TP-Link RE200).

On my home Wi-Fi: LG Content Store is not opening (error is -324 network is unstable); NetFlix in not opening (error nw-2-5); while YouTube is working normally.

On my mobile Hotspot (only used for the sack of testing): All apps are opening and are working well.

I tried all what I found on the Internet as potential solutions but nothing.
Please advise.

After 2-3 weeks of workarounds, trails, and tests; I discovered the fix. The issue was in the MTU value in the Router configuration.

MTU value ?

What is the MTU value that needs to be set.

I’m having the same issue

The MTU (maximum transmission unit) value is a parameter on the router configuration local page. MTU = 1460 worked for me.

Finding the optimal MTU value

First, thank you so much for finding this fix. I tried everything to solve this problem and lowering my router's default MTU value from 1492 down to 1484 solved my issue. Not only was it preventing connecting to the LG Content Store, but also playing Prime Video on my Amazon FireTV, and connecting to the PSN Store on my PS4.

I followed the steps on this article to determine the optimal MTU value:

What we usually do to fix it. As to why, ask LG.

PS. Other common fixes: Change the DNS to in the TV and connect to the router, not the extender.

Great fix

Thanks. After searching for solutions for a long time, speaking to LG (only option they gave was a factory reset or to send a technician to my house, for $40, I live in UAE), finally it works after changing the DNS to Nothing else did it for me, you’re a life saver.

Keep in mind this is not always the fix but keep it in your bag of solutions as it can really help naughty PCs and TVs.
