The Roon software on my 2 Macs and my phone will flash and blink, the images won't load, and I can't play anything. I have an MU1 and a Nucleus, and this happens on both. It is beyond frustrating and I really need help. My network is fine. Something is wrong with the software running on the server as I get the same errors and screen flashes on all my devices running Roon software. Can I go back to an earlier build? I am on server 2.48 build 1517 now using Nucleus. I have signed out of grimm MU1. One more thing the screen that lets me sign out of Qobuz is frozen such that it says EDIT where it should say logout. It won't change. The screen that shows my library will not show any images and it will say 0 of 2022 albums, but then it will flicker and show some images and say 2022 albums. It's crazy. I really need phone help with this. I am ready to give up on Roon after buying this crazy expensive MU1 server which I have now sidelined. Please help me. Just now things seemed to return to normal. I could play music. But it will be fine for a while then start with all the problems again.
Describe your network setup
cable modem to a router ethernet to all servers, wifi to computers and phone
Here are screen shots of the problem. Roon worked for several hours during the night, then out of nowhere this screen started to appear and I was no longer able to access anything!
So, as a test, I enabled the Nucleus server, same problem still exits. Flashing screen, 0 albums loaded, etc. I then transferred back to the Grimm MU1 server and all the same problems continue with the MU1, for a short time everything is loaded and functioning, then suddenly the albums disappear, the screen flashes and appears as it does in the screen images I have attached. I can use Qobuz independent of Roon with no issues. Also, these problems happen on every device whether MacBook, iPad or iPhone. I hope someone can tell me what is wrong.
Thank you for reaching out to Roon Support — it’s nice to see you again!
Could you kindly clarify how you migrated the database from one device to another?
To help us investigate further, please navigate to your Roon Database Location, locate the “RoonServer” folder, compress (zip) the entire folder, and upload it using our database uploader.
Thank you. It would appear that the upgrade to Roon 2.49 Build 1525 might have corrected the problems I have been having. I just completed the upgrade and things seem to be stable. I will give it a day and report back on what happens.
Well, I spoke to soon. I am intermittently having some of the same issues. As far migrating from one device to another, I didn’t migrate. I just disabled one device (MU1) and activated the other device (Nucleus). The list of albums saved was different because the Nucleus was inactive for quite some time, but I was just interested in the behavior of the Roon software. So, as I type this, the scene is flashing and has just now stopped playing altogether. Then, after a few minutes, maybe 10, it will start playing again. During all this pressing play would not do anything. On this screen I could not get Roon to play the album loaded. Maddening!
So, I have been listening for a couple of hours now. Things are seemingly more stable but the screen still flashes on and off at times, but no freezes since my last post. I am very interested in what is causing this instability. What could have caused so many problems to occur all at once?
Hi @GJ1,
I’m sorry to hear the issue has continued since the update. I think the next step here is to take a look at your logs. I tried to activate diagnostics on your server but the request didn’t go through. Can you please use the directions found here and send over a set of logs to our File Uploader? Once logs have been uploaded, please let us know so that we can check the server for your files, thanks!
In the meantime can you try navigating to Roon Settings → Setup and try to clear the image cache, does that help?
Thank you so much for your help. Since I am now on the Grimm MU1 server, I don’t know where these logs would be found. I had the unit turned off for a while, perhaps you could try again to access the logs. I cleared the image cache, but I can’t yet tell how difference it will make. The whole freezing, blinking thing could start back up. At this moment, I am playing music and there is no craziness going on. I hope you can access the logs or tell me how to find them with the MU1.
Hi @GJ1,
Fortunately, turning on the MU1 was enough for us to retrieve the logs—thank you!
I reviewed them and noticed some occasional disconnections from the client in the logs that predate your image cache clearing. Since things seem to be stable for now, please continue testing and let us know if the screen flashes or playback issues return. We’ll be here to help if they do.
Thanks for the update @GJ1 , let us know how further testing goes and if you notice the issue, please also note the exact local time + date of the occurance, this would help us narrow down the behavior in the logging.
