Samsung Smart TV no longer seeing raspberry pi media server

Hey everyone, I am hoping that someone might be able to help.
A recent issue has popped up when using my Plex media server on my Samsung TV. My RaspBerry Pi media server is available via Plex via web on my laptop, phone and steam deck but my Samsung TV is unable to reach it.

I have tried a hard resent on my TV and router.
I have restarted the Plex Media server itself.
Logged out and in on the App.
Switched the Client to allow IPv4 only to test instead of IPv4 and IPv6
I tried adding a custom server access URL so that it uses the IP and port.

No tweaks or changes so far seem to have helped and I am hoping that someone can offer me some advice here.

I recently updated the packages on my Raspberry Pi and I am not sure if this is related or not.

Any help here would be greatly appreciated and thank you in advance for the assistance.

If any additional information is needed please let me know!

Quick update here team, it seems that the Proton VPN that I installed locally on my Plex server caused issues with my DNS servers, I needed to update the DNS servers as these were modified.

sudo nmcli dev modify eth0 ipv4.dns “8.8.8.8 1.1.1.1”
sudo nmcli dev modify eth0 ipv4.ignore-auto-dns yes
sudo systemctl restart NetworkManager
