Description of Issue
Arc doesn’t connect. Fails test in app. I had my room core setup on an old laptop in the house and arc connected without any issues. Decided to change and try out the synogy NAS yesterday. Works well but can’t get Arc to connect. Error details attached
The diagnostics you’ve provided suggest that UPnP is enabled on your network, but your router is refusing the connection. This is either the result of UPnP not being enabled properly on your router, or settings at the level of your internet service provider.
First, to confirm the issue is not with your local network setup:
Try to enable UPnP/NATPMP in the web administration interface for the router directly upstream from your Core
Try to manually open the port in your router’s port forwarding configuration
Make sure the IP/Port matches the Port listed in Roon → Settings → ARC
Check for any VPNs or Firewalls that might be interfering
Check if your modem is in Bridge mode
If you continue to experience difficulties, we recommend reaching out to your internet service provider and passing along the following questions:
Have you implemented carrier-grade NAT for my account level?
Have you fully implemented IPv6, or do you have IPv4 addresses available?
Can I request a static IPv4 address to support port forwarding?
Are there any ports you have reserved at the ISP level I should be aware of?
Changing your core could be the reason. It’s possible that port forwarding / UPnP is set up for the wrong device now. Check your router configuration, and check that the IP address and port match what you shared in the image.
This is the exact issue. New Core is requesting a port that is already in use at router. It’s in use because your old core reserved the port. Either clear this in your router or change the port on new core to something not 55000 (like 55001).
