Router is a Linksys MX4000. No switches, no other hardware. Just the usual router and a mesh wifi.
Have tried the UPnP and it was already enabled so that didn’t work. I tried manually inputting the port forwarding, but that does not work either. The following error message below showed up.
I would suggest you create a manual port forwarding.
First in the zoon app under Settings — Roon Arc write down the ip address and port number shown there.
Watch below video and try it. Hope it helps.
There doesn’t appear to be a port mapping conflict in the diagnostics you’ve shared, so as @Martin_Webster mentioned, this 502 error is likely the result of either network security or an issue with UPnP.
A few additional troubleshooting steps you can take:
Disable any VPNs you might have active and double-check exceptions for firewalls and antivirus software to make sure they include Roon’s protocols
Verify the Linksys firmware is up to date. Outdated firmware can automatically disable UPnP on certain routers.
You mentioned a mesh WiFi network. Double-check that you don’t have multiple subnets active and that you’ve created an identical port forwarding rule to that in your Linksys web administration on any other router-capable device on this network.
If you have multiple ethernet ports on your Linksys router, try using your Core on another port. Sometimes, routers will disable certain protocols and features on certain ethernet ports. It’s worth a try.
We’ll be standing by for your response - please include any details prompted by our moderators that you haven’t already mentioned to expedite troubleshooting. Thank you!
Yeah, I don’t have the problem of VPNs or Firewalls being active. I’ve also checked with my router manufacturer and by default, there’s no firewall installed. It also already allows for VPN pass through, not that I have any VPN enabled.
I’ve also created the identical port forwarding and I don’t believe there’s any multiple subnet active. The error code again is this and if there are any multiple subnets, this should have shown up?
Lastly, I’ve switched the ethernet port too but also, that doesn’t work.
