Roon Remote can't find Roon Core after update (ref#0HRRPV)

Is Roon Server running?

· Yes, Roon Server is turned on and running.

What do you see on your screen?

· "Waiting for your Roon Server"

What happens if you press the "Select a different Roon Server" button?

· I don't see Roon Server.

Please try to restart your network setup by unplugging, waiting 30 seconds and then replugging in your networking gear.

· No, the issue remains the same

Please select how you've connected your Roon Server to the internet

· Roon Server is connected by *Ethernet*

Have you checked your firewall settings to ensure that Roon is allowed through?

· Roon still won't connect even after checking this aspect

Have you verified that Roon Server is on the same subnet as your Remotes?

· My Remotes and Server are on the same subnet and I still can't connect

Sometimes the issues can be resolved with a reinstall of your Roon Remote app. Let's try to perform a reinstall and see if it helps.

· I've reinstalled the Roon Remote but it did not help

What is the operating system of your Roon Server host machine?

· *Roon Optimized Core Kit* (ROCK)

Select any of the following components that are present in your local network setup

· None of the above

Describe the issue

After upgrading to the latest Roon Rock and Roon remote on various Android devices, the remote doesn't find the Roon Core anymore. If one enters the Roon Rock IP address into the browser on the Android device, it immediately connects to the admin dashboard of ROCK.

Describe your network setup

ROCK = Ethernet, Remote via WiFi, same Subnet, NO change to prior upgrade

Try rebooting everything.

Hi @Ralf_Hoellmann,

Thanks for writing in! Certainly, let us know if rebooting helps things, we’ll attempt to enable diagnostic mode on your Roon Server the next time it’s online and active with our servers.

Thank you! :folded_hands:

Hi Benjamin,

the server is up an running. Rebooting the server does re-connect, but only when the remote is in search mode. Once the tablet falls into sleep mode, the remote app doesn’t recover the server upon re-launch. Even when entering the IP address, no connection can be establsihed. It then needs the remote app kept in search mode and the server to manually reboot.

It have never experienced this issue before. It started directly after installing the latest updates for server and remote (I have also removed the remote from the tablet and re-installed it).

Lookjing forward hearing from you,
Ralf

Hi @Ralf_Hoellmann,

Thanks for the update! And, my apologies for not being more detailed above, did you also test out fully rebooting your router / any other network gear as well?

If not, please do this as well. Thank you!

Hi Benjamin,

network gear has been rebooted. Worked well on 1st try. Failed on 2nd and all consequtive.

Regards, Ralf

Hello @Ralf_Hoellmann ,

Thanks for letting us know. Can you please let us know the exact local time + date when the reboot resolves the issue, and then the local time + date when the issue next occurs? We’ll enable diagnostics for your account to see if there are any specific errors logged.

Hi Noris. Here you go. Different behaviour compared with error reported.

12.02.

07:40 pm CET: Server launched

07:41 pm CET: Remote app on TabS7 launched: Does not find server

07:42 pm CET: Remote app closed and re-launched: Does find server after about 20 seconds

Does this help?

Regards, Ralf

Hi @Ralf_Hoellmann,

Thanks for the time stamp! We can see the following error when your mobile device attempts to access Roon:

Warn: error processing internet discovery device 

Along with a Socket Crash (ReceiveFailure)

Warn: [easyhttp] [10] GET ... socketmsg (SocketError): Error getting response stream (ReadDoneAsync2): ReceiveFailure

The app was in the middle of receiving an image when the ROCK stopped talking. Because the app didn’t get an “End of File” signal, it threw a ReceiveFailure.

Can you please try the following:

  • Go to your Android Settings > Apps > Roon > Battery, and set it to "Unrestricted."
  • Toggle WiFi "Keep-Alive": Ensure your phone isn't set to "Disconnect WiFi when sleeping" or similar power-saving modes.
  • Check for IP Conflicts: Ensure 192.168.178.61 is reserved/static in your router. If another device is occasionally trying to claim that same IP, it will "kick" the server off the network momentarily.

Thank you! :folded_hands:

Cheers, Ralf

That’s great news @Ralf_Hoellmann - certainly let us know how things perform over the weekend.

Happy listening! :raising_hands:

Hi Benjamin,

situation is not really improving, At 08h10 CET (February 15th) it needed several re-boots of the server to get it up and running. It also failed twice connecting to Qobuz and Tidal.

What do you recommend next?

Regards, Ralf

Hi @Ralf_Hoellmann,

Sorry to hear it - we’re having issues connecting to your Roon Server to enable diagnostic mode, could you please share a set of manual Roon Server logs?

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!

Okay. Done.

Hey @Ralf_Hoellmann,

Thanks for sending those over! We’re seeing quite a few recurring network-related failures happening across multiple areas from your ROCK.

/login check network configuration: socketerr (NetworkUnreachable): Network is unreachable (172.66.148.147:443)

We’re also seeing some interesting Qobuz-related errors:

Warn: [qobuz] [http] error result from http request: {"status":"error","code":401,"message":"Current authenticated user is not authorized to perform this request"} 

You have my apologies if this has been glazed over, but could you test out using a different ethernet cable, as well as port, and see if you experience the same issues?

Thank you!

Hi Benjamin,

yes. You are right. Qobuz and Tidal errors occur also frequently. I have switched both, network cable and port on the switch. Will upload the new log.

Is this really better?

What about changing the IP address of the server?

Regards, Ralf

Hi @Ralf_Hoellmann,

You have my apologies here, but I believe you may be experiencing a known issue related to our upstream DNS providers, here’s the tracking link to the issues:

We don’t yet have any immediate next steps for you to troubleshoot, but the DNS maintenance shouldn’t last long.
