Fire TV stick, no playback

[pentolino 0]

I bought the streaming option for my Emby app on the Fire TV Stick, but streaming doesn't work; no video is played.

The server is accessed through a reverse proxy on a ssh tunnel forwarded remote emby and everything works fine using the web browser (either using the Silk browser on the fire tv or any other pc).
I sent a log through the app at 13.46 CEST, local user is Riccardo.

I am pasting the server log for that call, lots of errors there; full log is attached as well.

I am using embty server 3.4.0 and latest app version.

Hi there, can you please attach the complete emby server log? thanks !

[pentolino 0]

I think it didn't work before; let's see if it works now.

 

emby.txt.zip

[Luke 38825]

Is there any reason you're still on Emby Server 3.4 and not 3.5.2?

[pentolino 0]

No particular reason, I just thought it was an app problem (as confirmed by trying with 3.5.2, log attached: nothing changed)

emby.txt.zip

[Luke 38825]

Are you certain you're running the latest version of the fire tv app?

[pentolino 0]

1.6.15a, updated august 11th, 2018; as far as I know it's the latest

[Luke 38825]

Ok, we're looking into this, thanks.

[ebr 15435]

Hi.  Can you tell me exactly how you entered the app and how you logged into the user?

[pentolino 0]

I entered the app from the homepage, standard "clic"; I have automatic login, since I don't need more than one user. The user is correctly displayed on app home page

[ebr 15435]

Can you please try turning off the auto login, then exiting the app and logging in manually and then see if it works?

 

Thanks.

[pentolino 0]

I tried and still the same issue. I see from the stacktrace that the problem is missing user id; I guess the problem is that I am running without any kind of security, since the server is not on the internet (I only access it through ssh, so I have all the security I need)

What, exactly, do you mean by "no security"?

 

Also, can you please turn on debug logging on your server, then re-start the server and reproduce the problem and post that server log?

 

Thanks.

[Luke 38825]

How is your proxy handing request headers for the remote client ip address? It looks like it's stuffing multiple values into the request header, separated by commas.

[pentolino 0]

With "no security" I mean that there is only one user, the default one, and it has no password; that user is also admin.

As for the proxy configuration it is a virtualhost on apache2:

ProxyPass / http://localhost:8080/emby/
ProxyPassReverse / http://localhost:8080/emby/

So that this resolves correctly on the browser:

http://emby.alsette/web/index.html#!/home.html

(emby.alsette is the name of the virtualhost).

Debug log is attached

[ebr 15435]

Is it possible for you to test this without the proxy involved?  It looks like something is stripping a lot of the data that should be getting sent as well as the odd IP address (including the loopback).

[Luke 38825]

Yes first I think it is best to do a test without the proxy, then let's go from there. Thanks.

[pentolino 0]

I will try when I can, but if this is the case, why does every browser (including the standard one on the fire tv) work ok?

[Luke 38825]

Because different devices will react to different situations differently.

[ebr 15435]

And the browser may not actually be working exactly properly either.  I'd be interested to see a debug server log from browser playback as well.

 

Thanks.

[pentolino 0]

The app is working if directly connected to the server (no ssh tunnel, same network); is the playback function on the app using UDP by any case? This would be enough to justify why it doesn't work through the ssh tunnel (which only passess TCP through). The apache proxy seems to have no noticeable effect; browser works with or without it and app just doesn't, regardless.

 

I will send you a debug log about the playback on the browser; would it be possible for the app to fall back to the same method the browser uses if the first try goes wrong? I guess mine is not a common setup, but it is definitely a secure option for remote viewing (given you have a fast enough internet connection of course); will it evere be supported?

[Luke 38825]

No i think the vpn is messing with the request headers. Check the one that i mentioned. thanks.

[pentolino 0]

You didn't mention any specific header, which one(s) should I check? Also it's not a VPN, it's an ssh tunnel and it works at TCP level (bytes), not HTTP (text); I expect it to not know or do anything about headers.
The problem may be that the server is sending some value as the host (zotac.local) and the app expects it to be "emby.alsette". That is the host name is different if seen from the server or the app; for some reason this does not bother the browser though.

[Luke 38825]

see what it does with x-forwarded-for, x-realip,e tc.

[pentolino 0]

I actually moved my emby server on the same LAN as the fire tv (for reasons not related to emby) and the app works as expected.
Sorry I didn't get back to you, but I had little time to check this this out and I just don't need that anymore.

Thanks for trying to help me anyway
