Thread #1

CR Identifier: 998 NetworkTimeout
Means: Error in the message from Roon → our servers. Likely an Internet problem due to slow responses. Message from Roon → Server try this port and get back to me is not getting a response.

{
“connectivity”: {“status”:“NetworkTimeout”,“status_code”:998,“error”:“”},
“external_ip”: {“actual_external_ip”:“107.77.203.219”,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“status”:“NotFound”}
}


CR Identifier: 502 EHOSTUNREACH UPnP/NATPMP True
Means: Our server didn’t think it could find IP address it could sent data to. Something strange going on with your particular ISP situation. Made it to our server, but the server tried to connect to Core.

{
“connectivity”: {“status”:“NetworkError”,“status_code”:502,“error”:“error: Error: connect EHOSTUNREACH XXX.XXX.XXX.XXX:55002, response code: undefined, body: undefined”}, “external_ip”: {“actual_external_ip”:“94.XXX.XXX.36”,“router_external_ip”:null}, “natpmp_autoconfig”: {“server_ip”:“XXX.XXX.XXX.XXX”,“found_natpmp”:true}, “upnp_autoconfig”: {“status”:“NotFound”}
}

Suggestions:

  • Try to manually open the port in your router configuration
  • Make sure the IP/Port matches
  • Check for any VPNs or Firewalls
  • Reach out to your ISP

Thread #1

Means: Basically the same as a timeout. The router tells you to go away instead of talking to you. Might have UPnP enabled but only partially.

CR Identifier: 502 ECONNREFUSED UPnP/NATPMP WANIPConnection

{
“connectivity”: {“status”:“NetworkError”,“status_code”:502,“error”:“error: Error: connect ECONNREFUSED XXX.XXX.XXX.XXX:55002, response code: undefined, body: undefined”},
“external_ip”: {“actual_external_ip”:“XXX.XXX.XXX.XXX”,“router_external_ip”:null},

“upnp_autoconfig”: {“server_ip”:“XXX.XXX.XXX.XXX”,“found_upnp”:true,“error”:“Did not find UPnP service with WANIPConnection on network”}
}

  • Check to see if UPnP is fully enabled in your router
  • Try to manually open the port in your router configuration
  • Make sure the IP/Port matches
  • Update the router firmware

CR Identifier: 502 EHOSTUNREACH ConflictInMappingEntry

{

  • Port conflict mapping error, ensure no other apps are using the same port as Roon (or another Roon Core instance)

504 ETIMEDOUT

The port forwarding diagnostics you’ve provided suggest that UPnP is not properly configured on your router or not working correctly.

Please try the following steps in order:

  • Reboot your Roon Core and networking gear (router, modem, switches, etc.)
  • Try to enable UPnP/NATPMP in the web administration interface for the router
  • 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
  • Try to update your router firmware
  • Check if your modem is in Bridge mode and if not, try to place into Bridge mode

If you continue to experience difficulties, please tag the support team and include the following information:

  1. What is the make and model of your modem and router?
  2. Do you have any additional network hardware, like additional routers or managed switches?
  3. Who is your internet service provider and what is your geographic region?
  4. Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both?

Thanks!

998NetworkTimeout

The port forwarding diagnostics you’ve provided suggest that your Core is having difficulty reaching our servers. There are several independent factors that can cause this error, so we recommend double-checking the following to initiate troubleshooting:

  • Is your router firmware up to date?
  • Do you have any VPNs, proxy servers, or enterprise-grade security on this network?
  • Are you experiencing any issues with Roon Remotes, or other apps on your local network?

If you continue to experience difficulties, please tag the support team and include the following information:

  1. What is the make and model of your modem and router?
  2. Do you have any additional network hardware, like additional routers or managed switches?
  3. Who is your internet service provider and what is your geographic region?
  4. Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both?

Thanks!

502 ECONNREFUSED UPnP/NATPMP WANIPConnection

The port forwarding diagnostics you’ve provided suggest that UPnP/NATPMP is partially enabled but is not properly configured on your router.

Please first try the following steps:

  • Ensure that UPnP/NATPMP options are fully enabled in the web administration interface for the router
  • 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, please tag the support team and include the following information:

  1. What is the make and model of your modem and router?
  2. Do you have any additional network hardware, like additional routers or managed switches?
  3. Who is your internet service provider and what is your geographic region?
  4. Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both?

Thanks!

502 EHOSTUNREACH UPnP/NATPMP True

The port forwarding 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.

To confirm the issue is not with your local network setup:

  • Try to enable UPnP/NATPMP in the web administration interface for the router
  • 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?

Thanks!

Status: MultipleNatFound

The port forwarding diagnostics you’ve provided suggest there is a redundant layer of network address translation preventing port forwarding.

This can either be at the local-network level (commonly as a result of two routers), or at the level of your service provider (in the form of carrier-grade NAT).

If your setup involves an ISP-provided gateway (modem/router combination) and your own third-party router:

  • In the web administration interface of the ISP-provided gateway (modem/router combination), enable Bridge Mode or equivalent, where the ISP-provided gateway does not have DHCP routing enabled.

  • Alternatively, if you have already created a manual port forwarding rule in your 3rd party router, you can add an additional rule to forward the port through the ISP/second router.

If you only have one router in your setup or your modem is already in Bridge mode, please take a look through our list of known router and internet service provider solutions, as other users may have already encountered the same situation: ISPs and Routers: List of Known Solutions and Workarounds

You can reach out directly to your service provider to ask if they support port forwarding; this question will often enough to prompt them to explain whether or not the carrier-grade NAT they’ve implemented can function with ARC.

More specifically, you can pass 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?

If you’re unable to locate an existing solution in our #support:port-forwarding-resources subcategory, please reach out to the Roon support team and include the following information:

  1. What is the make and model of your modem and router?
  2. Do you have any additional network hardware, like additional routers or managed switches?
  3. Who is your internet service provider and what is your geographic region?
  4. Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both?
