Not sure why the app is not working.

I have several Samsung TVs and do not use that app as no app is required to use the plus channels. I have found that if I use a remote that has the numeric numbers on it it makes it easy to get to the plus channels. I am using an old Samsung remote from a previous TV but  a universal remote works fine also. Only needed to be sure the tv was connected to my wifi and I am able to just enter a plus channel number to get to the plus channel. You can go up snd down channels plus there is a button to get to the apps. Much better than the current remote they supply with the TVs now.

Hey, thanks for the reply.  Not sure I follow... there's no "app".  Samsung TV Plus channels are 1000+ on the Samsung TV.  Whether you navigate from the guide, from the Samsung Tuner, or directly by entering a channel number you are still navigating "to a channel."

My issue is that whenever and however I navigate to the channel I can load it, I can see the guide content and stuff about the channel, but the picture (video) will not resolve and I just see a black screen.  I can even see the audio meter on the guide moving with the active channels audio, which seems to imply that it's loaded and active but the video just wont display.

Part of me wonders if this is Samsung purpusefully deprecating old TVs from the STVP network by blocking the video feed, but that seems a bit to paranoid.

I thought STVP was a separte app you were using. I see now it is Samsung TV Plus.

I just got a another Samsung TV a few weeks ago and all I did was set up my WIFI, connect my outside antenna, and use the old remote with the numbers on it as the remote that came with the TV is not useful for the way we use the TV. Got all the channels including the 1000 plus ones. 

Have not had any issues with my old Samsung TV that is over 15 years old. I did replace another one that was 5 years old because of a picture going black. Did not want to fool with it for the cost of a new one. 

I would try a reset on the TV. I seen a web site that said to check the date and time plus a few other things. 

Can you get to the other apps such as Amazon Prime, Sling, ESPN, ... ?

Gracias por detallar tu caso. Es especialmente útil que indiques que estás usando un Archer AX55 V4 con firmware 1.1.2 Build 20241014 rel.59971(5553), ya que esto confirma que el problema ocurre en la última versión estable disponible.

He visto casos parecidos en los que Samsung TV Plus falla por cómo el router gestiona DNS o multicast, y te dejo algunas pruebas que suelen resolverlo:

1. Cambia el DNS en el AX55:
   • Accede a 192.168.0.1 → Avanzado > Red > LAN y configura DNS manual:
     • Google: 8.8.8.8 y 8.8.4.4
     • o Cloudflare: 1.1.1.1 y 1.0.0.1
   • Aplica cambios y reinicia el router y la TV.
2. Desactiva IPv6 de forma temporal:
   • Ve a Avanzado > IPv6 y desactívalo para probar. Algunas apps de Samsung tienen problemas si tu ISP entrega IPv6 pero no gestiona bien el tráfico.
3. Activa UPnP y revisa NAT Boost:
   • Avanzado > Reenvío NAT > UPnP debe estar habilitado.
   • Avanzado > Red > NAT Boost debe estar en ON para evitar cuellos de botella.
4. Conecta la TV en condiciones óptimas: Prueba por cable directo o en la red de 5 GHz del AX55 para descartar interferencias de 2,4 GHz.
   •  
   • Sincroniza hora y fecha en el televisor: Ajusta la hora en automático por red. Samsung TV Plus no carga canales si detecta desfase de hora.

Si con esto no se soluciona, te recomiendo abrir ticket directamente con TP-Link (ya que estás en la última versión de firmware) y adjuntar esta información. Es probable que ellos lo escalen al equipo de ingeniería para revisión de compatibilidad de multicast o IGMP Snooping en esta versión del firmware.

Mientras tanto, si necesitas usar STVP de inmediato, puedes conectar la TV al router antiguo como AP para que al menos tenga conectividad hasta que TP-Link lance parche.
