RoonARC "Poor Connection" Issues During Playlist Playback (ref#WT5LDK)

Hi! What’s not quite right with Roon?

· None of the above quite fits

None of the above quite fits

· App interface looks or behaves oddly

Tell us what's going on

· RoonARC has inconsistent "Poor Connection" issues. It will refuse to load a song citing Poor Connection. Yet it might play the next song in a playlist perfectly. No matter how many times stop the app, clear data and cache, it will never play a song once it claims there is a Poor Connection. Also, once it fails to load a song, it just stops the playlist rather than moving on to the next song. So rather than just starting a playlist and enjoying it, I'm constantly unlock my phone, go back into the app and move it along manually. For reference, my mobile connection is minimum of 4G with good coverage, and my home internet connection and ROCK have consistent good connection.

Tell us about your home network

This has been the case for as long as ARC has existed, FYI. You are not alone.

Hi @Stuart_Cadman

Thanks for the detailed description. To help us narrow down the cause of these intermittent “Poor Connection” issues with Roon ARC:

  1. Could you let us know which mobile provider you are using when you encounter this issue?
  2. Can you check if the same problem occurs when connecting to any other Wi-Fi network besides your home network?

Please note the exact time when the issue occurs next, and provide the song title and time interval so that we can review the diagnostic data.

This will help determine whether the issue is related to mobile/data connectivity, your home network, or something else entirely.

12/02/26 - 1305 Led Zeppelin Mix - 4G Vodafone coverage with good signal
played first song eventually
second song did not auto play - had to manually hit play
third song auto played
4th song did not auto play - several attempts to play, just timed out each time
skipped to 5th song - would not play
skipped to 6th song - would not play
skipped to 7th song - nope
skipped to 8th song - nope - and gave up trying
Tried Groove Armada mix - failed to play first song
second song would not play
then to prove connectivity was good I played a load of music from Youtube with no issues whatsoever…

I will see if I can get onto the wi-fi connection here and repeat

Hello @Stuart_Cadman

Thank you for the update.

From the diagnostic data, we see a bunch of errors related to the network connection from your mobile device to the core.

pq PLAYBACK_ERROR: "TransportError.playbackFailedOpen"
Unhandled flutter error:
HttpError [HttpErrorType.response]: 404 Not Found from https://xx.yy.aaa.30:55000/mobile/1/api/image/lhdfaaaa.4by3_512.jpg
pbe FTMSI-B-OE qo-202:9:10019530 "Get Down (Album Version)"-u34 rid:8 done (status:0 curl:42 'Unknown failure') interrupted:1 errorCode:ConnectionError

This suggests that the connection is unstable or being interrupted. To help us isolate and mitigate these networking issues, could you please try the following:

  1. Test a different Wi-Fi: Try using Roon ARC while connected to a different Wi-Fi network (not your home network and not cellular data) to see if the stability improves.

  2. Try Tailscale: If the issue persists, we highly recommend setting up Tailscale. This works as a secure tunnel that can bypass standard port forwarding and carrier restrictions, often resolving these types of connection errors.

You can find instructions on setting up Tailscale with Roon here:

Please let us know if either of these methods improves the playback stability.
