LG webOS TV not loading Plex app (Network Error -337)

[Noel Walker]

When trying to load the Plex app on an LGWebOs smart TV, app says :-

CHECK NETWORK CONNECTION    Error CODE : -337

This may be a temporary issue. 
Please try again later. 

(RETRY)     (EXIT APP)

 

• Firstly my network connection is fine. Netflix and YouTube loads and runs just seamlessly.
• This has only been happening in the last few months
• If I (RETRY) after a long wait sometimes it connects and loads correctly or I get the same error again.
• I have tried other Plex clients on my home server and they work just fine. 

Specs:

• LG OLED65C8PTA TV running Web OS 04.10.15.
• LG Plex client app is version 2.1.6 from Sep 2016
• Plex server is on my QNAP NAS and at version 1.13.5.291 from Sep 2018.

I guess my question is, if the LG Plex client app hasn't changed since 2016 and my Plex server is working for other clients, then what is going wrong?

Cheers

Hey. I had the same error and ipv6 didnt fix me problem, or even trying a different router.
I found this and it worked:

Not sure what your problem is but you can try xplay which is a plex client.  You can get it from the app store.  They keep it updated.  FYI:  my plex app works and I actually use both apps.  Sorry I can't be more helpful with your main issue.

@Noel Walker As the poster @dimitrislinuxos stated in his YouTube video, his simple solution worked.

Did you try it (you have nothing to lose):

Since I originally posted this question, several things have happened. I have had several different versions of the Plex Server App on my QNAP NAS, and also there has been an update to the Plex Client App on the LG TV. Anyhow the upshot of all this is that my Plex on LG has been working well for about 6 month or so now, and to be quite honest, I'm not sure what has resolved the issue. I did not try your method, only because my thought was if it is working now then don't change anything... ;-)

What you said in your YT video made sense though.
