Describe the issue

When using Roon (on MacOS 27), Roon freezes very often when looking up artists or similar. Search and response are slow. I tried to turn off throttle, but didn't help. After waiting a couple of minutes, Roon tries to reconnect. I also use a fixed IP address, just to avoid these malfunctions

Describe your network setup

Telenet Modem/Router F@ST3896LG-TN, Roon app connected via Ethernet. uPNP is disabled on the Telenet modem. For Roon ARC I use Tailnet to connect.

Hello @infotom

I have gone ahead and enabled diagnostics mode for your account and what this action will do is next time your Roon Server is active, a set of logs will automatically be generated and uploaded to our servers for analysis.

I wanted to reach out because I’ve been keeping an eye on our servers, waiting for the aforementioned diagnostics report.

For some reason it is not reaching our servers, even after I tried re-enabling diagnostics on your account. I also ran a quick test and I was able to submit a similar report from my setup here, so something else is going on.

So we can move forward, I was hoping for now you could use the directions found here and send them to our Logs Uploader Service and let us know after, thanks!

hi Vadim

I’ve uploaded the log files and gave it another name which is my mail address.

Looking forward hearing from you
