My Hisense TV previously picked up thumbnails and posters correctly through Plex but it has abruptly stopped doing so. It still plays back, and will even find theme tunes etc for tv shows but it just gives blank grey squares instead of artwork. If I connect to the server via browser on a laptop then it works completely fine, same for the Android mobile version.
I have seen this old thread - Bug report - cannot view thumbnails of tv-shows + movies in Plex on VIDAA - which pointed towards a networking or secure connection issue but it was never resolved there. All other threads with this issue always seem to point to problems with secure connections or SSL too, but again nothing ever seems to get resolved and I don’t understand that side of Plex well enough to troubleshoot myself.
Any help would be appreciated!
Server Version#: 1.32.6.7557
Player Version#: Plex for VIDAA 5.69.1
advanced → allow insecure connection - set to always
advanced → prefer insecure connections - never
On the Plex server
settings → network → secure connections - set to preferred
I have a VPN running on the same laptop as the Plex server - so I also set network → preferred network interface to my the local network (192.168.xxx.xxx)
I didn’t make any changes to certificate settings.
Thanks for the response, unfortunately it doesn’t seem to make a difference.
The only one of those I didn’t already have set was the “prefer secure connections” on the TV, the others were already set as you said.
I’ve tried looking at the debug log but it’s very hard to find anything that’s to do with thumbnails specifically. The only line I can find that seems to be relating to secure connections is:
“CERT: incomplete TLS handshake from 192.168.0.237:48234: sslv3 alert certificate unknown”
Just giving a bump here in the hopes of getting some attention - It’s been months now and still can’t get thumbnails to appear in Vidaa. The web and mobile clients work perfectly, just not on the smart TV.
Nope, still nothing on my end. A really frustrating part of this is that there are so few settings to interact with, so I don’t know if there is a solution that users could apply.
Alright, so it looks line I found the culprit on mine. I was setting up my router settings to be more secure and enabled the DNS rebind protection. This doesn’t work well with plex app when it tries to comunicate with the server. Setting it back to default rwstored the artwork.
Oh that’s fascinating. Unfortunately my router has absolutely no settings at all relating to DNS Rebind Protection (manufacturer does not want you to be able to turn it off) so I can’t try myself.
What specifically made you see a problem with the rebind protection?
I ask because I know that my server and TV are both set up to just use their local IP addresses to find each other. In fact I don’t think you can set the TV to look for a named computer rather than an IP address. However… Inside my router settings my server shows up as a nameless “Unknown” device, connected to “Other” interface even though everything else on the network can see its name and connect to it by typing the name into an address bar.
I had the same problem and thx to @Sergey, DNS rebind protection fixed it.
You do not have to disable it in your router, you can add an exception for plex.
Here the tutorial for FritzBox routers:
Go to Home Network → Network → Network Settings
It’s seriously frustrating that we can’t get ANY official word on this, because DNS Rebind is commonly not accessible on consumer routers, and there’s no obvious reason why it would interfere in any case.
