For the last week plex is taking 5 minutes to start on LG TV

Server Version#:1.42.2.10156
Player Version#:5.93.2

First it says Network Unavailable (even though it is) I leave it and it clears.
Then LG says plex startup is taking a long time to start.I have tried to restart but doen’t help so I just leave it.
5 minutes after first start plex comes up.
I have also noticed when switching from one episode to another it takes forever to update the description.
I have tried hard reset on TV and wireless router but didn’t help

Firstly look at your DNS. Change it too 1.1.1.1 and 1.0.0.1 in your router. Then restart everything, Server Router, ISP connection box, TV.

I should have said, other devices on the same network are working fine

Anyone able to offer any suggestions.
I have tied it down to 2 minutes saying no network then 2 minutes for plex to show anything. Sounds like 2x timeouts but can’t see anything in the logs
