Description of Issue

Almost every day, but not always, some of the CCA (chromecast audio) connections disappear from Roon. The Roon endpoints (my computer) and the Airplay do not disappear. To get them back, all I need to do is reset the server on-line (via the ‘find’ function in Roon) or walk over to the NUC running ROCK and reboot that. This works pretty flawlessly to restore function and then the CCA stay with me as I am using them the rest of the day. It is just very annoying to have to do this and others in my house are not willing to do the reboot and so just complain about roon and switch to Tidal directly. Thoughts? Of course, building Roon endpoints for everything would work, but I’m not there yet (but planning on using Pi4 endpoints once I figure out the setup).

Hey @Aaron_Thompson,

Thanks for taking the time to write in! It’s good to see you on community again, although I’m sorry it was an issue that prompted your visit.

Following up on your issue:

Do you know if they’re on wifi, or hardwired? This would be helpful info to know.

When this happens, do they still show up as available on your network? Or, do they also disappear from your network?

If you could please reproduce this issue and share the date and time of when the issue occurs, that would also be helpful. I’ll be on standby for your reply. :+1:

Hi Ben

Thanks for your response. I have one of the chromecast pucks hardwired (the one nearest my rock, which is also hardwired) and the rest are on wifi. It does not appear to matter though as often that one is absent as well or can be absent when other wifi pucks show up. All of the chromecasts remain on the network as I can still access them directly using tidal or spotify (by circumventing Roon). I recorded a sequence of events last night with images on my phone, times are at the top in 24-hr time eastern US. The date was 19 April 2023.

First we find that none of the CCA are visible on ROON. What we see below as options are the iphone I am using to take the picture, “Jenn’s new Macbook” which is on wifi and running roon remote, and tv room, which is an airplay connection.


Then I immediately went to the web server for ROCK and restarted the server. After a few minutes all of my CCA’s have now appeared [A&J room; Aaron’s Office (this is hardwired); Family room; Jenn office; and Kitchen]. All speakers is a grouping of all of the CCAs and it originates with Aaron’s office.



Then about 20 min. later the music stopped in the Kitchen for a moment and then when I checked most of the CCAs were not there (although Kitchen was still, so I just restarted playing it). This is fairly typical and usually doesn’t happen this quickly after restarting.


Thanks for your help. Right now I have my roon playing at my office and so my ROCK in unauthorized. I will re-authorize it in about an hour when I get home. I don’t unauthorize/reauthorize most days and there is no correlation with the (dis)appearance of the CCAs.

Hey @Aaron_Thompson,

Thanks for the follow up! It doesn’t look like the images you tried to add uploaded properly. Let me know if you’re able to give that another try.

With that, I’d like to refresh your RAATServer. Steps to follow below:

You can generate a new RAATServer instance on your device by following these instructions, but please be aware that this will reset your Roon Settings → Audio Tab to factory settings and I would advise making a backup of any custom DSP settings you have:

  • Create a Backup of your current Roon database
  • Exit out of Roon
  • Navigate to your Roon’s Database Location
  • Find the folder that says “RAATServer”
  • Rename the “RAATServer” folder to “RAATServer_old”
  • Restart the Roon App to generate a new RAATServer folder

Let me know if you still run into issues after the above. If yes, I’d like to take a closer look into your router and router settings. What DNS is your router currently using? I would also verify that both Roon.exe and RAATServer.exe have been added as exceptions to any firewall or third party security software.
