Describe the issue

I can login to ARC and it sees my Roon Core but when I connect to the core, it gets stuck on the Syncing with Core for the first time. I do this with my phone connected to my home's wifi. Roon settings page shows ARC to be ready, and it also shows with a green circle in Roon ARC. I also verified I can indeed connect to the ARC port from outside my home (using telnet).

Describe your network setup

I have NetGEAR Wifi Mesh setup as my router. My Roon core is connected with ethernet to one of the satellites. Roon operation itself is seamless and has no issues.

Hi @phi4,

Thank you for your post. Diagnostics show that the session layer for ARC has lost authorization - we have work that will soon be released to prevent this sudden unauthorized condition from occurring, but I recommend reinstalling the app and attempting onboarding once more on your local WiFi.

Please also note that sync can take up to 5 minutes or more with a larger library. If sync failures continue to occur after re-authorizing the session, please let us know and we’ll investigate logs to learn more.

Thank you!

I did try uninstall/re-install over local wifi, but the problem continues. I realized after several minutes it drops out of the sync and goes back to the previous Roon Core selection page.

any update on this? I am still unable to use Arc due to this issue.

Hey @phi4,

Thanks for the update. Based on your library size, Arc could be failing when attempting to process all ~300k tracks.

It would be good to test to see if you run into the same issue on a completely fresh Roon database, even if only temporarily. Steps to follow below:

  • Create a fresh backup before anything else
  • 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 Roon Server” and connect to the new database

Before restoring your backup, see if you’re able to connect and sync with Arc, or if you run into the same issue. We’ll be monitoring for your reply. Thank you! :raised_hands:

I did this test and I could connect to Roon ARC using the empty library. Should I try to restore a backup into this wiped library?

Hi @phi4,

Yes this is the next step now that it works with an empty library. Please let us know if ARC works properly after!
