Jellyfin, Fire TV Sticks, Server Unavailable - "Unable to respond to udp request because the local ip address could not be determined."

[evoelise]

I have been using Jellyfin 10.4.3 running on a Ubuntu 18.04 VM, viewing using browsers on couple of PCs and a couple of Fire TV sticks for over a year now with no problems.

But now, this week, the 2 Fire TV sticks have both stopped working, when I launch the fire stick Jellyfin app it asks me to select a server and I select the JellyFin server (the FireTV stick shows correct hostname and port) but this just comes back with the message "Server Unavailable".

When I do this I see the warning [WRN] Unable to respond to udp request because the local ip address could not be determined. in the JellyFin logs several times.

Using a browser from my PC to attach to the JellyFin server still works fine. I can see and ping the IP name and address on the JellyFin. I can ping the two Fire TV sticks. These are all on an internal network on the same subnet.

The only change I have made recently was to move the media to an UNRAID server from a Windows File server. But I don't think this is the problem as I can still view all the media from the PC browser fine.

Things tried; restarting FireTVSticks, restarting JellyFin server, restarting VM, restarting ESX hypervisor host, restarting network switch, reinstalling JellyFin app on one of the FireTVSticks. None of this has worked.

What would cause the Unable to respond to udp request because the local ip address could not be determined.? The Fire TV Stick can obviously be seen by the JellyFin server as it gets the UDP request, but why can't it determine its local IP?

Would you mind upgrading to nightly to verify bug?

Would you mind upgrading to nightly to verify bug?

Do you mean upgrade JellyFin to nightly or JellyFin-Andriod client? I can do the former but if the later do you have instructions on how to upgrade the FireTV stick to a given release?

[evoelise]

Guessing you meant upgrading the JellyFin server to nightly.

I have done this but the FireTV sticks are still not working. However now the JellyFin server shows no log message at all when the FireTV sticks try to connect.

[Artiume]

Ok, with unraid, are you using docker?

[evoelise]

No, I have the JellyFin Server v10.4.3 running on a full Ubuntu 18.04 O/S.

It is just the media that resides on the Unraid server.

In network settings, what network mode do you have? Set it to disabled

[evoelise]

I have it set to "Preferred but not required". I have set it to "Disabled" now but the FireTV sticks still can not see the server.

[Artiume]

You have to restart jellyfin to make the changes take effect

[evoelise]

After setting Secure Connection Mode to "Disabled" I have restarted the Jellyfin server, the FireTV stick and the Jellyfin Android client. It is still not working.

[Artiume]

Hm... What about ipv6? Is there anything else in your network settings?

[evoelise]

What about IPv6 as far as I know it's not in use here, the FireTV sticks appear to only use IPv4? I have turned off IPv6 on the Jellyfin server just in case and restarted but it is still not working.

Networking Settings

LAN networks: Bind to local network address: Local HTTP port number: 8096 Local HTTPS port number: 8920 Allow remote connections to this Jellyfin Server: checked Remote IP address filter: Remote IP address filter mode: Whitelist Public HTTP port number: 8096 Public HTTPS port number: 8920 Base URL: /jellyfin Custom SSL certificate path: Certificate password: Secure connection mode: Disabled Enable automatic port mapping: unchecked

remove the base url

[evoelise]

I have removed the base URL, it is still not working.

[Artiume]

@nielsvanvelzen @thornbill you guys have any ideas? I'm fresh out. Like 5 ideas ago 😅

[thornbill]

Did you restart the Jellyfin server after removing the base url? I believe any changes to the network settings require Jellyfin to be restarted to take affect. Having base url set does break the autodiscovery on 10.4.x because the server address returned does not include the base url.

[evoelise]

I did restart the server yes.

I created a new VM from a fresh Lubuntu 18.04 install, fully updated and reinstalled Jellyfin. Server discovery on the FireTV stick now works and I now see both servers. But now I'm stuck on the next part - when I select a server it the Android app asks me to "Select User" but there are no users to select.

[thornbill]

:+1: Thanks for confirming. I am glad you got it working although I am still curious what was causing your issue initially. I have not seen that error before.

As far as being able to view users, for improved security defaults the users are hidden by default. You can manually enter them in the app or change that setting in the server's admin dashboard. https://jellyfin.org/docs/general/server/users/adding-managing-users.html#additional-options

I am going to close this since your initial issue seems to be resolved, but feel free to continue the discussion or open a new issue if you continue to have questions or problems!

[mlaggner]

well, this security feature just cost me about 3 hrs of research on my FireTV stick. Would be at least helpful if there is a text field to enter user names per hand on the FireTV app... (android worked oob)

[nielsvanvelzen]

You can manually enter users, there is a very big button for that.

[mlaggner]

this is everything i get on the latest Jellyfin app from the Amazon store if there is not at least 1 user available which is not hidden:

and if I choose the server which is provided from auto discovery, I only get "Server unavailable"
