Apologies for the delay in my response! Thank you for reaching out for assistance with port forwarding. I’ve split your post into a separate thread so the team and other users can assist you more directly.
Typically, errors like the one you see can be caused by a misconfigured Port Forwarding setting, if you are not seeing Ready listed in Roon Settings -> Roon ARC, please look over this guide before proceeding.
If you have reviewed this guide and still have not resolved the issue, can you provide the following details about your network setup to help expedite troubleshooting?
Who is your internet service provider?
Please list the make and model of your modem and router?
Do you have any additional network hardware, like additional routers or managed switches?
Does your network have any VPNs, proxy servers, or enterprise-grade security?
What machine are you using as a Roon Core, and how is it connected to the internet?
Nothing has changed in my setup and I’ve been using Roon ARC with no problems since release. Now, I can’t get ARC to connect to my Roon Core. Port forwarding has been set up manually etc.
Hi @Glen_Giffen
Could I trouble you to share screenshots of the Arc settings page in Roon Remote and also one of the screen with the port forwarding rule. The error to me still suggests it’s not set correctly.
Glen have you tried a restart of your Roon Core.
I have had this issue a couple of times myself and between restarting the Core and my phone (if needed), it has mostly fixed it
YEs, first thing I did was to restart the Core and the phone. Also uninstalled and reinstalled Roon ARC on my Samsung phone. Thanks for the feedback Michael
Ok good start, I have seen the moderators for other connection issues suggesting to go into ARC settings and choose Reset Roon ARC, I had to that not long after it came out of beta, but I don’t like suggesting it.
Not sure if you are on iOS or Android, but of on Android, I have also had to uninstall and reinstall a couple of time’s in the 5 months of testing and live (or clear the storage) though you lose all your download files then.
Thank you for bringing your issue to the attention of the Community.
If you’ve set a manual rule, I’d verify that the port hasn’t changed in Roon → Settings → ARC, and that it still matches the port you’ve assigned in your router web administration.
Do you have any firewalls engaged on your local network? What about other network security?
I’d also verify that a router automatic reset didn’t disable or reconfigure UPnP, if ARC had been relying on that protocol.
Looking through recent Community history, we’re not able to verify if this issue was solved for you. Has port forwarding been successfully automatically configured with a more recent version of ARC/Roon? We’ve made a number of improvements since you first reached out.
If you want to give manual configuration another shot, we’re here to support you. Otherwise, this topic will autoclose within the next week. Thank you!
Recent diagnostics from ARC show cellular connectivity, but there’s also a warning trace suggesting you might still be having issues syncing with your Core.
If that remains the case, and you haven’t tried a database refresh already, please take the following steps to fully refresh your NUC’s credentials with ARC:
First, create a Backup if you don’t have a reliable recent backup of your database already. This will make sure you don’t lose library content, DSP settings, etc.
Rename the “RoonServer” folder to “RoonServer_old”
Restart the RoonServer in the WebUI to generate a new Roon database folder
On the Roon Remotes, press “Use another Core” and connect to the new database
From there, you may have to redesignate the port assignment in Roon → Settings → ARC if you’d set up a manual port forwarding rule in the Nighthawk router. We’ll be here to support and keep a lookout for your post.
