Arc not connecting after router unplugged

[Christian_Platt]

After having to unplug my router as part of moving furniture etc, I now cannot get Arc to connect to my core. On the Arc tab in settings on my iMac (the core), I just have the word ‘Testing’ and a circle spinning round. There is also no Roon Core IP address in the afforementioned Arc tab. I have reloaded Roon on the iMac/core and deleted the Arc app on my iPhone. Neither have worked.

I keep reading about ‘ports’ etc on routers, but I have not had to do this previously as my core and Arc connected without issue when I first got Arc. Furthermore, I have no idea what ‘ports’ means when talking about routers etc.

Any help would be appreciated.

I moved your post from #uncategorized to #support:port-forwarding-help. As you posted in #uncategorized, you didn’t see the template that is shown by default in #support:port-forwarding-help. Therefore please tell us what your setup is:

Roon Core Machine

Include your operating system and machine info (Model, CPU, RAM)

Networking Gear & Setup Details

Your network gear (model of routers/switches), if on WiFi/Ethernet, and if you are using a VPN

1. Who is your internet service provider?

2. Please list the make and model of your modem and router?

3. Do you have any additional network hardware, like additional routers or managed switches?

4. Does your network have any VPNs, proxy servers, or enterprise-grade security?

Hello @Christian_Platt
You may have used UPnP. In this case, it may be sufficient to reboot your core machine, and possibly also to restart the Arc remote.

Expanding on what @Axel_Lesch mentioned:

@Axel_Lesch

and possibly also to restart the Arc remote

you also may want to reset the ARC remote app by selecting the Settings option (the gear icon in the top right corner) in the ARC app and scrolling to the bottom of the page where a red “X Reset Roon ARC” option is available.

I noticed this issue a while ago and commented on it, as did @Tim_Rhodes.
For me, a core reboot of my Nuc was enough to get everything working again.

B1208 Roon ARC UPnP configuration fails after ISP internet outage

Just to confirm, I had exactly the same issue with ARC from day one: As soon as I had to reboot my router or just the modem for some reason, the connection via UPnP regularly stopped working afterwards. A core reboot fixed this with UPnP and ARC working again. I did not try to reboot only the server. (That’s why I configured a port forwarding rule for my router instead of UPnP, so everything runs perfectly now without any interruptions or failures.) My router: ASUS RT-AX86U Modem in bridge …

Hi Axel,

Apologies for the late response. I have rebooted my core, but can’t restart Arc after uninstalling and then reinstalling the app. After signing in, Arc aknowledges my core, but won’t connect and just stays on the 'trying to connect ’ screen with the wheel spinning. Am at a total loss as to why I can’t connect.

In the meantime, there were quite many other posts where ARC setup is showing “testing” forever. May be unrelated to your setup. Roon is investigating, some of it was caused server-side and it was partially resolved but apparently not yet competely:

ARC Not Working Since Update 1223 [Roon Investigating]

Hi @Sean_Pierce and @Tyrone_Milton, The team can reproduce the symptoms you’re reporting. We have an open investigation and will resolve the underlying server-side issue as soon as possible. We don’t anticipate you should continue to experience these problems for long, as we’ll stabilize the backend processes responsible for the loss of service. Other users have resolved the issue or found a reprieve from the spinning port forwarding test by 1) rebooting their Core device fully and/or 2) unins…

ARC Not Working Since Update 1223 [Roon Investigating]

Hi everyone, The team continues to investigate the underlying issue here. Some users may experience reduced symptoms now that server stability has been restored; other users may continue to be affected for the time being until we release an additional fix. We’ll provide an additional update as soon as we have a more precise timeline to resolution.
