Old Samsung TV failing to connect to Server

[pattang_21 4]

Hi,

 

Since you are all batting at 1000 with my previous issues I have full confidence you can sort this out where I have failed miserably for an hour.

 

A friend of mine is running an old Samsung TV. It was connected to my old emby server without an issue. I have upgraded server and now am running it through NGINX. It works with every other person I have on the server except this person. He consistently has an issue where it says there is a "Connection Failure" when attempting to login on the TV app. This occured when he attempted the Emby connect PIN method and when he attempted to just connect manually to the server.

 

However he can login everywhere else (Meaning iphone and computer). I have looked this up on the forum and it suggests that it is a firewall issue but he believes there isn't one on the TV since the last server connected just fine. For context the last server connected via the remote access IP address and emby connect (which doesn't seem to work now that the server is on NGINX)

 

Any thoughts about I can go about getting him connected?

 

Thanks in advance

Hi there, are you using https on your server?

Hi Luke,

 

Yes I am. But other Samsung tvs don’t seem to have an issue so I assumed that wasn’t the root cause.

It will vary significantly from one model year to the next. The older the unit, the older the certificate store that it has and the less likely that Samsung is still updating it. @SamESmay have more insight as he's done extensive research on this.

So I think it is able to connect, but the TV is not accepting the certificate. Unfortunately this forces you to make a difficult decision in terms of whether to have your server require https or not.

Can you give us the model number of the one that doesn’t work and maybe one that does?

Who is the certificate issuer?

Hi SamES,

According to him the model number is UA60JU7000. As for a model number of a new one what works I don’t have one but they are all much newer. (He says this is one of Samsung’s first 60 inch 4K TV’s) 

 

As for the certificate it’s a custom one from Cloudflare. 
 

Thanks for the help

Thanks.  J-series is very old now, 2015.  Can you check which Certificate Authority (CA) has signed the Cloudflare certificate?  It's quite likely that the original root certificate on the TV has expired and can't be renewed.

After September 9th, 2024, Cloudflare will serve all Let’s Encrypt certificates using the ISRG Root X1 chain.

Quote

Cloudflare will stop issuing certificates from the cross-signed chain and will instead use Let’s Encrypt’s ISRG Root X1 chain for all future Let’s Encrypt certificates.

The change in the certificate chain will impact legacy devices and systems, such as Android devices version 7.1.1 or older, as those exclusively rely on the cross-signed chain and lack the ISRG X1 root in their trust store. These clients may encounter TLS errors or warnings when accessing domains secured by a Let’s Encrypt certificate.

Hi,

 

He realised that he has a firestick so he is just using that now. Thanks for the help though.
