This article is a sub-section of Troubleshooting the IXrouter connection using LED status codes, specific for IXrouters that are connected via Ethernet cable.

Wired connection

Wait at least 2 minutes for the IXrouter to finish booting and attempting to connect to the IXON Cloud. Select what the Activity (ACT) LED status is after these 2 minutes:

• (ACT) Constant red
• (ACT) Blinking red 1 pulse
• (ACT) Blinking red 3 pulses
• (ACT) Blinking red 4 pulses
• (ACT) Blinking red 5 pulses
• (ACT) Blinking blue 1 short pulse
• (ACT) Blinking blue 1 long pulse
• (ACT) Blinking blue 2 short pulses
• (ACT) Constant blue

(ACT) Constant red

Description
The IXrouter is booting, which usually takes ~1 minute, or is not registered.

Solution
Register the IXrouter. If you just attempted to register the IXrouter using a USB flash drive, this status means that the IXrouter didn't recognize the USB flash drive or didn't find the file "ixrouter.conf". Make sure that:

• the USB flash drive is formatted as FAT or FAT32. File system exFAT is not supported.
• the configuration file is named "ixrouter.conf".
• the configuration file is located in the root directory of the USB flash drive.

Upon insertion of the USB flash drive, the IXrouter's ACT LED should blink blue quickly, indicating that it's reading the configuration file and configuring itself. If you don't see this happen, double check the steps above or try a different USB flash drive.

If the problem persists, try to factory reset the IXrouter.

(ACT) Blinking red 1 pulse

Description
The IXrouter is unable to reach the IXON Cloud.

Try the following first. It may enable your edge gateway to reach the IXON Cloud without further troubleshooting.

• Try configuring a fixed DNS server in the WAN settings.
  • Enter 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare DNS).
  • This can be configured while leaving the other WAN settings set to DHCP.
  • If this does not resolve the issue, revert the settings to what they were previously and continue below.

Make sure that the IXrouter has internet access:

• Check the connection by unplugging the Ethernet cable from the IXrouter's WAN (internet) port and plugging it into your computer. Turn off any other connections on your computer, like Wi-Fi.

If your computer had internet access in the test above, then the IXrouter may not be configured correctly. If you just used a configuration file, open the configuration file with Notepad or simply create a new one. Alternatively, you can also check the current WAN Ethernet settings on the IXrouter's local web interface. Make sure that:

• the WAN (internet) settings are correct for internet access in the local network. Letting the IXrouter obtain an IP address automatically (DHCP) will be suitable for most situations. If you configure a static IP address instead, be sure to always consult the local IT administrator for the correct network settings (IP address, network mask, default gateway, and DNS server).
• proxy server settings are correctly configured, if applicable.

Make sure that the IXrouter is allowed to reach the IXON Cloud:

• Check with the local IT administrator that the company firewall is not blocking the IXrouter's attempts to reach the IXON Cloud. Details can be found at: How does your device connect to the IXON Cloud? (ports, protocols & servers).
  • Tip: use the IXON Check to test the local network and provide insights.

(ACT) Blinking red 3 pulses

Description
There is a LAN/WAN conflict in the IXrouter settings. In other words, the LAN (machine network) IP range and WAN (corporate network) IP range are the same or IP-technically considered to be a part of one another. This means the IXrouter cannot differentiate between the two and cannot reliably determine which way is "the internet".

Solutions
There are a few solutions to this situation that you can choose from:

• Change the IXrouter's LAN IP range by creating a new configuration file with the same WAN settings, but a different LAN IP range than before. Note that you will also have to change the IP range on your connected hardware, like the PLC.
• Change the IXrouter's WAN IP range by choosing one of these options:
  • Ask the local IT administrator if there is a different IP range or VLAN available to which you can connect the IXrouter for internet access.
  • Use an IXrouter 4G/LTE model in combination with a cellular connection instead of the current wired connection.
  • Place a router, this can be any router you have lying around, between the corporate network and the IXrouter's WAN port. Configure that router such that the IXrouter will receive an IP address in a different IP range than before and for it to also have internet access.

(ACT) Blinking red 4 pulses

Description
The IXrouter was removed from the IXON Cloud.

Solution
The IXrouter needs to be registered again without rebooting the IXrouter. If the USB flash drive with the configuration file is still in the IXrouter, simply take out the USB flash drive and insert it again, without rebooting the IXrouter. If you do reboot the IXrouter, wait for the ACT LED to start blinking red 4 pulses again and then insert the USB flash drive with the configuration file.

(ACT) Blinking red 5 pulses

Description
The IXrouter is trying to register itself in an IXON Cloud company, but there is still an old registration from the IXrouter listed in that IXON Cloud company. This situation usually happens when someone has factory reset the IXrouter and immediately tries to register it again.

Solutions
There are two solutions to this situation that you can choose from. If you want to re-use the settings from the old IXON Cloud registration:

• Turn on "Recover upon next registration".
• Do NOT reboot the IXrouter. If you do, wait for the ACT LED to start blinking red 5 pulses again before continuing.
• Take out the USB flash drive and plug it back in.

If you do NOT want to re-use the settings from the old IXON Cloud registration:

• Remove the device from the IXON Cloud.
• Do NOT reboot the IXrouter. If you do, wait for the ACT LED to start blinking red 5 pulses again before continuing.
• Take out the USB flash drive and plug it back in.

(ACT) Blinking blue 1 short pulse

Description
The IXrouter has internet access and is trying to reach to the IXON Cloud.

• Check with the local IT administrator that their company firewall is not blocking the IXrouter's attempt to connect to the IXON Cloud. Details can be found at: How does your device connect to the IXON Cloud? (ports, protocols & servers).
  • Tip: use the IXON Check to test the local network and provide insights.

Description
The IXrouter's VPN connection is manually disabled.

Solution
If you keep seeing this LED status it means that the IXrouter's VPN connection is manually disabled.

• Enable the VPN connection. Depending on how it is disabled, through its Digital Input or through the IXON Cloud, use that same method to enable it again. Details can be found at: Switch VPN on/off.

Description
The IXrouter is initiating a VPN connection to the closest IXON VPN server.

Solution
If you keep seeing this LED status it means that the IXrouter is unable to establish the VPN connection.

Try the following first. It may enable your edge gateway to connect without further troubleshooting.

1. Try Stealth mode.
   • This masks the edge gateway's VPN traffic as regular internet traffic (HTTPS) and may allow your edge gateway to connect.
   • Configurable at Fleet Manager > Devices > Click on your device name > Network > VPN.
   • Once enabled, make sure to reset or unblock the error message so your edge gateway will try to connect again. This may take several minutes, depending on the situation.
   • If your edge gateway successfully connects, you can continue to use this workaround or proceed with the steps below to find and resolve the root cause. The latter is recommended to find a proper solution instead of using a workaround.
   • Stealth mode may have a marginal impact on performance. Though this if often not noticeable in practice.
   • If your edge gateway does not connect, turn Stealth mode off and proceed with the steps below.
2. Try VPN connection type UDP.
   • This makes your edge gateway use a different port (1194) than with TCP (443) and may allow your edge gateway to connect.
   • Configurable at Fleet Manager > Devices > Click on your device name > Network > VPN.
   • Once enabled, make sure to reset or unblock the error message so your edge gateway will try to connect again. This may take several minutes, depending on the situation.
   • If your edge gateway successfully connects, you can continue to use this workaround or proceed with the steps below to find and resolve the root cause. The latter is recommended to find a proper solution instead of using a workaround.
   • VPN connection type UDP does not negatively impact the performance or functioning of the edge gateway.
   • If your edge gateway does not connect, set VPN connection type to TCP and proceed with the steps below.

The following solutions are situation dependent and may not all be relevant to you. Don't forget to reset or unblock the error message after trying a solution so your edge gateway will try to connect again. This may take several minutes, depending on the situation.

3. In Pakistan, the Pakistan Telecommunication Authority (PTA) requires that every VPN connection to the outside world needs to be registered for VPN to work.
   • Information about the procedure can be found on the PTA website: https://www.pta.gov.pk/category/ip-whitelisting-&-vpn-registration. For assistance in this process, contact the PTA themselves or a local authority.
   • Part of the form that you will receive is about the VPN connection. Click below for help.
     Form help

4. If you're in a different country that you know or suspect to have banned or restricted VPN usage (e.g. Egypt), contact your local Internet Service Provider (ISP) for assistance in allowing VPN for the edge gateway.
5. Try disabling IPv6.
   • Applies to IXrouter models only.
   • The IXrouter normally falls back to IPv4 when it's unable to connect using IPv6, but in networks that do not have IPv6 fully set up correctly, this may not always be the case. Disabling IPv6 then forces the IXrouter to use IPv4.
   • This change cannot be done remotely, only on-site. If this is not possible, but the IXrouter does have a VPN connection (with Stealth mode on), please contact us. We can then disable IPv6 for you remotely.
6. If the above solutions have not resolved the problem, a firewall is intentionally or unintentionally interfering with the edge gateway's connection attempts. This is most common with a wired or Wi-Fi connection, but has occasionally also been observed with cellular connections. Contact the local IT or Internet Service Provider (ISP) and explain the situation using the problem description at the beginning of this article. Also include the following support article, explaining how the edge gateway connects to the IXON Cloud and listing potential firewall settings that are known to block or interfere: Ports, protocols, and servers used by the edge gateway.
   • Tip: use the IXON Check to test the local network and provide insights.

(ACT) Constant blue

Description
The IXrouter has an active VPN connection to the IXON Cloud.

Solution
If you see the IXrouter listed in your IXON Cloud company, but it doesn't have an active VPN connection:

• Hard refresh the webpage (CTRL+F5 for Windows users).

If you do not see the IXrouter listed in your IXON Cloud company:

• Check if you are currently looking in the right company. You can switch company by opening the account menu in the top right corner and selecting [Switch company].
• Check with the person who invited you to see if you have access to this IXrouter.

If the above is correct, but you still don't see the IXrouter, then it may have previously been registered in a different company.

• If you wish to save its previous configuration, you can transfer the IXrouter.
• If you do NOT wish to save its previous configuration, you can factory reset the IXrouter and then register it again.
