Description of Issue
ARC is enabled on the core and I have been running it since it was released. Normally it works well and I really like this feature addition to Roon. However, lately I have been receiving frequent ‘Poor Connection’ alerts on ARC when my iPhone is on both wifi (in my house) connection and on cell/data connection (5G). Tracks will then no longer play on ARC. Often ARC works fine for long periods of time, then poor connection error starts. After some investigation, Poor Connection seems to happen because the core has become unresponsive. I’ll navigate to the home page on the core and the Roon logo spins and there’s no response. Eventually I will restart Roon and then it loads/works properly for a period of time. However sometimes I have to restart a few times because the spinning logo state returns. It seems to happen randomly.
Secondary feedback: ‘Poor Connection’ is a frustrating error to receive in ARC. Is it connected, or not? what does ‘poor’ mean? My connection became too slow suddenly?? When on cellular service, I use the Balanced playback option. I also have tracks downloaded to my phone. I also often get ‘Poor Connection’ when I switch to play downloaded tracks. Does ARC have to have a connection to my core to play downloaded tracks?
This also happened to me on Thursday. It just stopped playing and said poor connection when I had 50mb/s download on 4g and my home network was fine as I could connect via other apps I have. Got home still didn’t work via ARC on home network. Went to Roon app got the jellyfish like you. Logs show lots of issues with the iPhone remote losing connection yet it didn’t say anything at all. A restart of Roon server and it’s back to normal. So yes I believe something in ARC is hanging the core.
Three times I used ARC outside of the house, and three times it caused the core to hang. Once it played fine for a couple hours, then ‘Poor Connection’. Another time it lasted 10 min.
Hi Benjamin. Poor connection was happening consistently (every time I used ARC) but then the issue went away for about a week. It happened once again a couple days ago, but otherwise the problem seems to have gone away. I didn’t make any changes on my end. If it happens again I’ll note the date and time.
Hi Benjamin. I’ve experienced the poor connection pop up and posted on other threads. It has been 100% fail rate in the last few days, a lot worse than normal. Not sure if it’s worth mentioning, but when the core hangs it also prevents the nightly backups from completing if I don’t restart the core.
‘poor connection’ happened:
25-Jul around 5:10 pm EST track London Calling by the clash.
25-Jul around 7:20 pm EST track Killing in the Name by Rage against the machine
26-Jul around 10:05 am EST
26-Jul around 12:20 pm EST
27-Jul around 10:15 am EST
27-Jul around 5 pm am EST (‘poor connection’ appeared upon my first attempt to play a song)

you have my apologies - I’m not able to pull a fresh diagnostic from your core device to better investigate any underlying issues.
Could you please reproduce the issue, share the date and time, and then use the directions found here and send over a set of logs to our File Uploader?
As luck would have it, ‘Poor Connection’ hasn’t happened in the last few days. The first day I noticed it was stable was July 29, using ARC outside of the house on both wifi and cellular connections. I have since traveled overseas and it also worked via wifi abroad. I am home again and I will monitor on cellular connection over the weekend and submit a log if ARC crashes the core.
Hi @Benjamin,
I still get ‘Poor Connection’ periodically (on average once a week). Today it happened twice, so I uploaded the logs just now.
FWIW, I was using Arc around the yard, and my connection to wifi was on and off. Each time I would lose wifi (switch to cellular) it would stop playback. I turned off wifi on my phone and was just on the cellular/data signal. At random moments play back would stop and I then upon resuming I would get ‘poor connection’. After restarting Roon on my core, Arc would work again.
Something else I noticed is that my cellular signal would switch between 5G and 5+. I wondered if this also caused ‘poor connection’ but I didn’t see when 5G would switch to 5+ and vice versa.
I only took note of the second Poor Connection occurrence: between 6-7 PM EST.
Thanks for the update! We’re currently investigating Arc issues related to the symptoms you’ve been experiencing. I hope to have more information to share soon.
In the meantime, if you head into your Arc settings, what does your internal storage space look like? I’m seeing frequent memory pressure errors that may be playing a role in things.
Thanks for your report! We’ve created a specific tracking thread in which we’ll be posting all future updates to the issue here:
Our team is still investigating things, so unfortunately, I don’t have any next steps for you at this time. I appreciate your patience while we continue to troubleshoot.
