Problèmes de connexion après mise à jour du 27 avril 2026 (ref#JRSHT0)

[Fred_Dumas]

Hi! What’s not quite right with Roon?

· Can’t reach my Server, remotes or ARC

Can’t connect to my Server, remotes or ARC

· Other ARC issues

Tell us what's going on

· Mon système a fonctionné parfaitement jusqu’à ce que j’essaie de faire la mise à jour publiée le 27 avril 2026.
Le système s’ouvre normalement. On m’a alors demandé de mettre à jour tous les devis et je l’ai fait. Quand j’ai relancé j’ai eu le message qui disait que “ impossible de trouver votre serveur”. J’ai attendu 10 min et toujours pas de connexion réseau. J’ai ensuite essayé de me connecter Roon sur Mon Mac, là il le trouve mais quand n’arrive pas à se connecter.

J’ai redémarré tout mon équipement numérique sans succès.
Comme dernier effort de fossé, j’ai supprimé l’application roon de mon MAC et j’ai réinstallé et toujours aucune connexion réseau positive.

Please contact 432 Evo for a firmware update, Roon Server needs updated system components to run. See also:

Roon 2.65 and ARC 1.77 are Live!

Hey Everyone, This is a major release for us, and an important step forward for Roon. We’ve migrated the platform underneath the app to a newer foundation, which improves performance today and gives us a much stronger base for the work ahead. In practical terms, that means better efficiency, reduced memory usage, and a platform that gives us more room to keep improving Roon in the releases to come. You should feel that work in everyday use. RoonServer now uses memory more efficiently and retur…

It might be a good idea to include the information about the changed requirement in the message to 432 Evo.

Salut. J’ai le même problème

[Fred_Dumas]

[yann_pautel]

Même problème avec mon serveur Nas…

Please don’t hi-jack other users support threads with your own issues.
Please create your own tickets instead if a forum search doesn’t already reveal a solution.

There are currently two OS versions in the field for 432 EVO music servers:

1. a now discontinued OS based on fedora linux which we have supported for 10+ years, and for which we cannot provide a patch to satisfy the glibc and openssl requirements. Support for the old OS has concluded end of 2025.

2. a more recent enterprise grade Linux OS since the summer of 2024, which fully supports Roon’s Linux requirements = 432OS, and which 432 EVO will keep supporting.

Users need to contact 432 EVO or their reseller for this upgrade, and this upgrade will be possible for any user even going back to servers sold since day 1.

[Fred_Dumas]

Je vous ai contacté ainsi que ALL IN MUSIC il y a quelques mois pour connaître les démarches pour faire la mise à niveau et je n’ai pas eu de réponse.

Je vous ai envoyé également un mail hier matin et j’ai appelé mon revendeur qui a du vous contacter.

J’attends maintenant vos réponses pour pouvoir faire en sorte de mettre enfin à jour mon EVO.

En attendant, je n’ai plus de musique. J’espère que vous serez être plus réactif cette fois-ci.

Hey @Fred_Dumas,

Both @BlackJack and @Frederic_Vanden_Poel are correct here. You’ll need to get in touch with 432 Evo directly, since they are the only ones who can provide the firmware update you need for your server.

There is nothing Roon can do on our side in this case, unfortunately. If you can, please continue working with 432 Evo on the upgrade path for your EVO. We know this has left you without music, and that is a rough place to be.

Once that update is in place, the Roon connection issue should be resolved.

[Herbert_B (Herbert Buchsbaum)]

Thank you. I will be speaking to the seller today. As for contacting 432 Evo, I see no way to contact them and zero customer support on their site.

@Herbert_B

I see no way to contact them and zero customer support on their site.

@Frederic_Vanden_Poel is the designer and he’s here on the Roon forum. He posted here in this thread just a few posts up.

[Herbert_B (Herbert Buchsbaum)]

Yes, I know. And he said “users need to contact 432 EVO.” He did not say how to do that and the EVO site has no apparent way of contacting them.

[Suedkiez (Just a fellow user like you)]

As I tagged him again above, I hope he’ll respond here. There is also contact info here:

Dealers - 432 EVO Music Servers | High End Digital Audio Streaming

[Herbert_B (Herbert Buchsbaum)]

Following the dealer’s instructions, I went to VortexBox, clicked on VortexBox Upgrade > Start Upgrade. After a couple of minutes, it said “Update Complete. No need to reboot; nothing was updated.” I rebooted anyway, checked the configuration page and it said Roon was not running.
So what now?

[Fred_Dumas]

J’ai réussi à l’avoir par mail il y a 3 jours à info@klinktbeter.be. Normalement il faut voir avec le revendeur. Vous avez acheté le EVO dans quel magasin ?

[Frederic_Vanden_Poel]

This is incorrect advice.

We do not offer 432OS via an internet update.

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?

· *MacOS*

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

· None of the above

Describe the issue

Roon remote is unable to locate Roon server. Had been working fine yesterday.
I've tried all the suggested fixes: I've rebooted the host computer, the iphone controller, the Roon device, the wifi router. I've checked the subnets and masks on the iphone and computer (though not the Roon device, which I don't know how to do). I've reinstalled a fresh version of Roon on my phone.

Describe your network setup

My Roon Core device is a 432 Evo Standard music server, remote is an iPhone 17 Pro running iOS 26.3.1, host computer is a Macbook Pro M1 running Sequoia 15.6.1. Router is Xfinity X.B8.T.
