ARC "Poor Connection" Errors Only Resolved with Core Restart

[Barry_Scotton]

My core is a NUC5i5RYH with 8gb of RAM and a 250Gb M.2 drive.

OS ROCK, Windows or Linux?

[Barry_Scotton]

It’s Roon Rock

I had issues like this in the early betas, but over the last few months it has been rock solid for me.
I do generally close my open apps before starting ARC as like @Simon_Arnold3 said it does seem to be a memory hog. My phone has 16GB of RAM so that might really help

It’s definitely the ROCK core at fault, I have 2 ROCK cores at each of my 2 residences, same hardware it happens at residence 1 using my Android phone but not residence 2 with the same phone.

Residence 2 was restored using a backup from residence 1 when I came back to here last month so when I go back to residence 2 in a few months I’ll see if a reinstallation of the core fixes it.

Interesting. Thanks raf

ARC "Poor Connection" Errors Only Resolved with Core Restart

Yes it’s a weird one. I dont know if it’s an Android issue or not but unfortunately i dont have an Apple device to try. It’s frustrating because Arc works over 4g/cullular on my phone no problem and plays music for a while. Sometimes It’ll play 10 tracks, another time it’ll play more but ultimately i always eventually get the poor connection message rendering Arc unuseable. The other annoying thing is that whenever this happens, Roon at home becomes unresponsive and i have to reboot my NUC core…

As stated in the closed topic I have returned to my other residence where this problem occurs and now ARC won’t play any songs, the Core has been updated to the latest version.

I’ll try a complete reinstallation of the Core OS and report back.

Hi @raf,

We’ve pulled diagnostics on the Core since you’ve attempted the reinstall, and a few things stand out:

1. This ROCK can’t access the network shared storage location. The CIFS mount is failing because the network is unreachable - this might be a firewall/security/permissions issue, or it may be that you need to double check how you’ve configured the storage location to the network and verify it’s on the same subnet as the ROCK.

2. You’re encountering an unfortunate known error whereby restoring a ROCK from Backup causes connectivity issues with Roon Remotes. A known workaround is to restart the ROCK 2-3 times and see if it changes the connectivity conditions.

We’ll take a look at ARC diagnostics in the meantime. Thank you!

Hi Connor,
I’m not having any issues accessing the shared storage locations, I have to edit the IP address after restoring the backup due to the network at my other rersidence using a different subnet and yes I did have issues with the Roon Remotes but as you say restarting the ROCK a few times fixed that.

[raf]

Just tried out ARC after the reinstallation and back to original issue, plays 3 tracks and then Poor Connection error and unable to access Core via ARC or Remotes (local network) without a Core restart.

[Barry_Scotton]

Exactly my issue.

[raf]

Worked OK today, it did come back with a Poor Connection error after 1 song but after a restart of the phone app it continued to play where it left off, so may have been a different issue, after that I was able to play two complete albums.

[raf]

Had a different issue today, it playted 3 and half songs & stopped and came back with a playback error and then wouldn’t continue playing coming back with usual poor connection error, an app restart caused the app to stall and coming back with error saying it’s taking too long to respond so a forced restart fixed that issue and then it played back fine after that.

So problem that required a core restsrt seems to have disappeared having not happened for 2 days we’ll see if the new error continues.

Hi @raf,

Thank you for the updates and for your patience in awaiting a staff response. Rest assured we’re investigating these reports as we work to improve stability in ARC.

More recent logs are revealing network dropouts on your Core, followed by failures to reach ARC. There’s also evidence that the Core is experiencing a build mismatch, potentially interfering with connectivity to both ARC and Roon Remotes.

Let’s first stabilize conditions on the Core by performing a backup and database refresh. Please take the following steps after verifying your Core has access to the backup location on the network share and performing a manual Backup:

• Stop RoonServer from running in ROCK’s WebUI
• Navigate to your ROCK’s Database Location
• Find the folder that says “RoonServer”
• Rename the “RoonServer” folder to “RoonServer_old”
• Restart the RoonServer in the WebUI to generate a new Roon database folder
• On the Roon Remotes, press “Use another Core” and connect to the new database

Please let us know if this changes any of the symptoms you’re experiencing.

Hi Connor,

I followed the steps and only added one folder of music and had no issues at all today, I’ll add all my music to the database overnight and see how it goes tomorrow.

[raf]

A couple of minor issues today which may well have been more related to cell connection than Roon, one required an app restart and one I just needed to press play again, so looking good.

[raf]

No issues today, so it would appear the issue was a build mismatch in the database.

Is it possible to get the the history and stats from the old database into the new one?

Also is it not advisable to backup from one machine and restore to another?
