Roon ARC connections problems

I have my Roon core installed on my Apple iMac. It all works perfectly on the roon endpoints in my home. Also, on the Roon ARC tab in the interface, it says “Ready” and that “Roon ARC can securely access your Roon Server.” Also, I have the Roon ARC app installed on my iPad and iPhone, and both said that they synced with my Roon server.

But when I open Roon ARC whenever I am away from home network, either on my iPad or iPhone, it wlll not connect and I get a message that my Roon server cannot be accessed.

My Roon core/server is connected to the internet via an ethernet cable direct to my modem/router. The connection speeds are 310 mbps download and 350 mbps. upload.

What is the problem? How can it be fixed?

Is there any way I can get some help on this issue?

Hi @Jack_Cobetto,

Thank you for your patience while we worked through the queue to reach you.

Your iMac appears to be pinging Roon’s servers via multiple network interfaces. Do you have both ethernet and WiFi active on this machine? What about a VPN installed on the iMac?

In the meantime, unless you have a specific reason to keep it on, I recommend disabling IPv6 in your iMac network settings.

We’ll follow up shortly. Thank you again.

OK, I turned off my wi-fi connection to my iMAc. I will see if this helps.

How do I disable “IPv6” in my Mac network settings. I don’t see it anywhere. (Is it the same as disabling the wireless connection?)

Am I ever going to get a response from Roon about the above??

I have to say that Roon ARC strikes me as. very poor feature compared to how well Roon works in my home.

Hi @Jack_Cobetto ,

The instructions may differ a bit depending on your exact Mac, but please see below on how to disable IPv6 and let us know if this helps, thanks!

  1. Open System Preferences and click Network.
  2. Select your network connection on the left, then click Advanced on the right.
  3. Go to the TCP/IP tab.
  4. Next to Configure IPv6, select Off from the drop-down menu.
  5. Click OK, then Apply to save the changes.
  6. Repeat the same steps for any other network interfaces you want to disable IPv6 on, like Ethernet.

How to turn off IPv6 on Mac?

When I get to the Configure IPv6. tab, I am given 3 options. - “Automatically”, “Manually” and “Link- Local Only”.

I am not given the option to turn it “Off.” What should I do?

Can you help with this?

Hi @Jack_Cobetto ,

Please give the Link-Local Only option a try, it seems like Mac changed the option in later releases:

Hello there, indeed I can confirm that the IPV 6 on Local did the trick for me! I updated last night to latest version ROON and had according the ROON ARC no access - how ever outside our premises running our 4/5G ROON ARC works flawlessly despite the wrong ! information!

So now by putting IPV6 to local I do see the server IP and ROON ARC is ready to connect.

above before the setting change IPV6 wrong information but ARC was accessible

IPV6 set to local and now a good view for ROON ARC thank you Support!

Describe the issue

I cannot use Roon ARC to connect to Roon from networks other than my own network. I also cannot use Roon ARC to connect to Roon on my cell phone. Roon ARC keeps generating messages saying "cannot connect to Roon server". I have complained about this, was given suggestions that did not work, and was finally told to wait for an update that would likely fix the problem. I waited, and downloaded the update, and it did nothing. The same problem persists. I'm getting very frustrated. Are you going to help with this?? I have made many posts on the "community " on this. Please read them so I don't have to repeat myself yet again.
