# Troubleshooting

## LED indicators

The Efento Gateway is equipped with four LEDs that provide visual feedback about the device’s status. These LED indicators help you monitor the gateway’s operation and identify issues quickly.

The meaning of each LED color and blinking pattern is described below:

<table data-header-hidden><thead><tr><th width="275.90625">LED</th><th>Status / Meaning</th></tr></thead><tbody><tr><td><mark style="color:blue;"><strong>Blue – quickly blinking</strong></mark></td><td>The gateway is connected to the mobile app and ready for configuration.</td></tr><tr><td><mark style="color:blue;"><strong>Blue – slowly blinking</strong></mark></td><td>The device is trying to establish a network connection. If this step is taking too long, check the Ethernet cable to ensure it’s securely connected.</td></tr><tr><td><mark style="color:blue;"><strong>Blue – constant</strong></mark></td><td>The gateway is connected to a network.</td></tr><tr><td><mark style="color:orange;"><strong>Orange – quickly blinking</strong></mark></td><td>The gateway is in configuration mode and waiting for a connection with the mobile app.</td></tr><tr><td><mark style="color:orange;"><strong>Orange – slowly blinking</strong></mark></td><td>No loggers are currently within the gateway’s range.</td></tr><tr><td><mark style="color:orange;"><strong>Orange – single blink</strong></mark></td><td>The gateway button has been pressed.</td></tr><tr><td><mark style="color:green;"><strong>Green – blinking</strong></mark></td><td>The gateway is actively communicating with the server.</td></tr><tr><td><mark style="color:green;"><strong>Green – constant</strong></mark></td><td>Communication with the server completed successfully.</td></tr><tr><td><mark style="color:red;"><strong>Red – constant</strong></mark></td><td>An error has occurred. Contact support at <a href="https://help.efento.io">help.efento.io</a>.</td></tr><tr><td><strong>All LEDs blinking sequentially</strong></td><td>The device is powering off, resetting to factory settings, or clearing memory.</td></tr><tr><td><strong>All LEDs flashing simultaneously</strong></td><td>Critical error. Contact support at <a href="https://help.efento.io">help.efento.io</a>.</td></tr></tbody></table>

## Troubleshooting using the Status Page

Most issues can be quickly identified and resolved by reviewing the information shown on the **Status** page. In general, communication problems between the gateway and Efento Cloud or a custom server are caused by either **network configuration errors** or **server-side issues**. Follow the steps below to diagnose and resolve the problem:

1. **Start by connecting to the gateway and checking the** [**Status page**](/efento-gateways/ethernet-gateway/status-page.md)**.**\
   Review the **Network** and **Server Status** fields and address any issues indicated there.
2. **If you cannot access the gateway through its IP address, try pinging it.**\
   If the gateway does not respond, it may be using a different IP address than expected.\
   In this case, [**restore the factory default settings**](/efento-gateways/ethernet-gateway/other-settings.md#reset) and configure the device again.
3. **If network settings appear correct (Network Status = OK) but communication with the server still fails** verify that your [**firewall settings**](/efento-gateways/ethernet-gateway/network-settings.md) allow communication with all required Efento services / your custom application.
