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.

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
