Issue description

A DNS resolution error occurs when pushing local Playlist to provider. UI says its unable to sync and to contact support. Logs say it’s unable to resolve host.

I’m able to sync (pull) from navidrome, but I can’t sync (push) to navidrome.

Navidrome successfully records now playing, streaming file, scrobbled events, but there’s no logs associated with the Playlist sync.

Device type

Phone

Media provider

Subsonic (Open)

Steps to reproduce

Select Playlist
select sync
select push local version to provider

There’s no logs uploaded …

The issue is as most duplicated that you configured the host as http, and your server auto redirect to https and in that case drop the POST data.

Fix your provider settings.

I didn’t realize the logs were greater than the 100MB limit but I do have the provider configured correctly:

I need proper full logs

5

I generated more logs and uploaded them. The DNS error appears to have been related to the Wireguard VPN that’s always on. I disabled it and now I’m getting a different error.

Corresponding Navidrome log:
{ “time”: “2026-08-17T13:10:50Z”, “level”: “warning”, “msg”: “API: Failed response”, “endpoint”: “/rest/getPlaylist.view”, “error”: “70”, “message”: “playlist not found”, “requestId”: “e68e317b8101/dalk6avurU-271997” }

The playlist does exist as I was able to pull from provider but I’m trying to remove duplicates and re-upload it.

The logs you uploaded is another issue …

2026-08-17 10:48:24.189 Verbose SubsonicLogger ← [748] HTTP FAILED: java.net.SocketTimeoutException: timeout

And if the servers returns an error saying not found then you have your answer. The id probably changed you deleted / recreated / restored or whatever. You need to delete on Symfonium then import again.

I confirmed the playlist ID is correct, but I deleted/reimported it anyway and now get a different error:
2026-08-17 11:38:08.098 Verbose/SubsonicLogger: ← [278] {“subsonic-response”:{“status”:“failed”,“version”:“1.16.1”,“type”:“navidrome”,“serverVersion”:“0.63.2 (be10f89c)”,“openSubsonic”:true,“error”:{“code”:0,“message”:“number of URL query parameters exceeded limit”}}}

The log file is 160MB so it’s too large to upload, do you have a preferred alternative location to upload it that will accommodate this size?

8

it’s all in the docs :wink:

And again the id is either wrong or you have a redirect somewhere that drop the POST data.

Probably the 2nd as with Navidrome playlist are updated via post and only fallback to get if it fails.

9

I’ve uploaded new logs, it is using POST this time but still failing due to the above message.

10

Then you need to see with @deluan if there’s any limits in Navidrome for the post data and how to change it.

11

Yes, there are limits by default, imposed by the GoLang runtime. But there is a way to configure it.
