Pano Scrobbler with LZ enpoint

[wazabees]

Me again. This time, I'm setting up a Fiio DAP that plays music stored on an in-device SD card. I use Poweramp to play my music, but it's limited to Last.FM scrobbling, or via SimpleScrobbler. I also have Pano Scrobbler (version 4.38) on my DAP, and Pano seems to require an HTTPS connection. I set up my reverse proxy, and I'm getting some error messages.

I read issue #416 , and my error looks a bit different.

Using https://ms.domain.com:

[2026-05-01 12:55:59.172 +0200] WARN   : [App] [API] [Ingress] [Listenbrainz] Received what looks like a Listenbrainz Endpoint request but it was to an invalid URL route: /1/user/Multi-Scrobbler/playing-now

I don't know where Pano Scrobbler got /1/user/Multi-Scrobbler/ from.

Using https://ms.domain.com/1/:

[2026-05-01 13:01:50.735 +0200] WARN   : [App] [API] [Ingress] [Listenbrainz] Received what looks like a Listenbrainz Endpoint request but it was to an invalid URL route: /1/1/validate-token

And my config, which works with navidrome:

    {
      "name": "myLz",
      "enable": true,
      "data": {
        "token": "token"
      },
      "type": "endpointlz"
    },

Am I configuring this wrong? I haven't tried with a Last.fm endpoint in multi-scrobbler yet.

The 1/user/Multi-Scrobbler/ is part of the listenbrainz api spec but multi-scrobbler doesn't support it, currently. It hasn't caused issues with other clients, they usually just ignore the error and try to submit scrobbles anyway (at a route that MS does support).

If pano is failing to submit, entirely, due to the now playing route being missing (I guess its short circuiting its scrobble logic?) then I can add a stubbed out now-playing route pretty easily to fix this.

[wazabees]

Scrobbles are being submitted, yes. I think it's just me seeing lots of error messages and it makes me feel like the connection between multi-scrobbler and Pano is fragile. ;) I'll leave it running and if I encounter any actual errors, I'll open an issue - thank you! :)

It was easy enough to add! You can try docker image foxxmd/multi-scrobbler:pr-580.

pr-580 also includes proper username handling so the username returned to lz clients is no longer hardcoded to Multi-Scrobbler. It is now based on your source's name (myLz) or you can configure it yourself in the source config via username. You may need to reauthenticate/reconnect with panoscrobbler because of this.

Thank you! I tested it, pr580-47c600e, and it is indeed the source name. Should multi-scrobbler still warn about this? :)

Make sure base URL path to MS endpoint is correct.

It looks like pano is trying to get a lot more info that isn't needed for just submitting. Is it affecting its useability or is it just warnings you see in MS, at this point? If it's just the warnings its safe to ignore them.
