Samsung TV Jellyfin App suddenly unable to connect to server

[Manly Manlison]

Hi. I have a Jellyfin 10.8.10 server set up with a Duckdns reverse proxy, that had previously worked flawlessly for the user, but for the last few days they have not been able to connect to my server anymore, I've tried reinstalling the app but I am not sure why it would stop suddenly. 

Anyone else having recently trouble?

Did your IP change? Do you have the DuckDNS agent installed to update your IP?

[Manly Manlison]

No, my IP hasn't changed. Any other client still works, it's only with the Samsung TV (Tizen) app.
It still works with Android, iPhone, LG TV, PC and browser.

Can you share your full jellyfin log? Sanitize any WAN IPs and user names. Upload it to pastebin and link it back here.

Before I do that, I tried checking the logs myself when trying to connect with the Tizen client App but it did not show anything on the server side.
There's a lot of shit in the logs so it'll take a looong time for me to sanitize (don't know how to do it automatically, so I'd have to do it manually)
