Yatse can't connect to Jellyfin Nightly (built from source)

1024mb · May 31, 2020, 3:14am

Issue description: I sent you an email concerning this and till this day I got no response, so I’m trying to get one here. When trying to connect to Jellyfin built from source Yatse says: “Unable to get server version”. I’m using Jellyfin version 10.6.0 unknown (that’s what the Dashboard says) on Windows 10 x64. I’m using Yatse 10.2.5/3110804-arm64-v8a with license.

Additional information: I have found one (I think) similar problem happening with jellyfin-mpv-shim, see: #63

I’m using direct LAN IP: 192.168.100.xxx

Is this something that can be solved?

Without the mandatory logs there’s nothing I can tell

And no sorry I never received any logs or mail regarding your issue.

1024mb · May 31, 2020, 7:41am

Oh, damn, sorry. Here is the log: debug-20200531_022953.zip (2.6 KB)

To add more info: I can enter the server from Firefox (on the phone, of course).

Well yes they broke their internals

[228] GET http://192.168.100.155:8096//System/Info
2020-05-31 02:29:45.000 Verbose/JellyfinLogger: <-- [228] 500 Internal Server Error http://192.168.100.155:8096//System/Info (19ms, unknown-length body)
2020-05-31 02:29:45.001 Verbose/JellyfinLogger: <-- [228] Access token is required.

@anthonylavado is this a known error? Returning error 500 for auth issues is wrong as it’s a generic error and no one can renew tokens from that.

anthonylavado · May 31, 2020, 5:07pm

Passing this around internally. Is there a reason for the double slash here?

http://192.168.100.155:8096//System/Info

Probably because you now normalize the path and return “/” as a sub directory in the discovery packet

Will look and try to remove on my side but this never have generated issues before.

1024mb · June 3, 2020, 3:01am

Passing thru to say that this problem doesn’t happen with Jellyfin 10.5.5.

Tolriq · June 3, 2020, 7:05am

Yes it’s an bug or wrong internal change they made on Jellyfin side.

The error should be 401 so that Yatse or any other remote renew token. No one on error 500 will parse the message to try to see if it talks about token and renew or add the token at that time.

@1024mb how old was your build ?

Wonder if Fix 500 error causing first-time setup wizard to hang · jellyfin/jellyfin@3bc07e7 · GitHub did fix your issue, else @anthonylavado there’s some other place where the same kind of fix will be necessary.

1024mb · June 9, 2020, 8:21pm

@Tolriq If I remember correctly when I tested and created this topic my build didn’t have more than 2 days old and according to that commit date it would have been already included.

I have built Jellyfin today and tested Yatse with it and it could connect to the server, but I suppose that is happening because I have been previously authenticated to the server already, right? I should delete the server from Yatse and add it again?

Tolriq · June 9, 2020, 8:33pm

Yes starting fresh is a better way to know.

1024mb · June 9, 2020, 9:12pm

I deleted all data on Yatse and started the app. I got the same error as before. This time I’ve checked the Jellyfin logs and found this:

Yes same as before @anthonylavado needs to find the one who made the change and fix to the proper missing place on Jellyfin.

AuthenticationException must return error 401 not 500.

I have not found a public issue on Jellyfin tracker so no idea what is going on their side. Nothing actionable on Yatse side.

anthonylavado · June 11, 2020, 4:08am

We’ll look at it. 10.6 isn’t releasing yet as it is.

anthonylavado · June 11, 2020, 4:27am

I can’t really comment because I’m not close to the server code, but I’m getting those who are to look into it. Looks like 500 was an old Emby fallback. We formatted it nicer, but it’s still there: jellyfin/Emby.Server.Implementations/HttpServer/HttpListenerHost.cs at 998d5674a2bf82c6f83b566a2acfd8aadad59ab9 · jellyfin/jellyfin · GitHub

Tolriq · June 11, 2020, 7:55am

@anthonylavado

There was a change in auth error to be more precise and AuthException now.

Some part of the code do not know about it and so do not properly handle it now

Fix 500 error causing first-time setup wizard to hang · jellyfin/jellyfin@3bc07e7 · GitHub have fixed one case for example. I’m pretty sure it’s just a matter of finding the other places that catches SecurityException but not AuthenticationException

anthonylavado · June 11, 2020, 1:40pm

Tolriq · June 14, 2020, 7:03am

@1024mb does this fix your issue so I can close here?

1024mb · June 18, 2020, 4:10am

Sorry for the late response, I’ve built Jellyfin right now and tested it. That fixed the authentication problem, I can now use Yatse with Jellyfin 10.6.0.
