No telemetry displayed in the RAPT Portal

| **Telemetry may not have been received - this depends on the device's Telemetry Interval.** Wait at least 60 minutes for telemetry to be received | | |

Device may not be registered. Navigate to the Registration screen on the device or Captive Portal. If Registration has been successful this will display the message REGISTRATION DONE! If registration was not successful then this will display the MAC Address and Validation Code. Re-register the device

NOTE: The firmware of the RAPT device must be up to date before registration

| | | **The device may not be connected to WiFi.** Navigate to the Diagnostics screen of the device or Captive Portal and check that the device his currently connected to WiFi | | | **Signal Strength may be too low/intermittent.** Check your signal strength. Please refer to the [SIgnal Strength Graph below](#signal-strength). Signal Strength can be checked in the expanded graph in the RAPT Portal | | **Error when registering RAPT device** | **Firmware may be out of date.** Select **Check for new firmware** in the **DIagnostics** or **Setting screen** *before* registering RAPT device | | | **Token timeout.** The **Validation Code** token may have timed out. Reboot the RAPT device. Log out of the **RAPT Portal** and log back in | | | **Network issue.** Ensure the RAPT Portal is open on a device connected to the same WiFi network as the RAPT Device. *If the Captive Portal is open on the device, it is not connected to the internet and Registration will not work.* Open the RAPT Portal on a separate device such as a laptop or tablet | | | **Firmware issue.** A corrupt firmware install can prevent registration. This can happen if a firmware download is interrputed, for example. If the above steps do not allow registration, please refer to [RAPT Device Boot Loop Troubleshooting & Recovery Mode](/equipment/rapt-brewzilla-or-user-guide/rapt-device-boot-loop-troubleshooting-and-recovery-mode.md) to rollback firmware to a good version, then update to the current version | | **Cannot see a Validation Code** | **RAPT device not connected to WiFi.** Connect the device to your WiFi network | | | **Firmware may be out of date.** Select **Check for new firmware** in the **DIagnostics** or **Setting screen** *before* registering RAPT device | | **Cannot update firmware \| 5379 Error** | **This is a network issue.

Check your signal strength against [this table](#signal-strength) | | | **Other Network issue.** Make sure there are no VPNs in use, or filters or other potential issues set up in the router that can block an outgoing signal | | | If issues persist, reboot the device and also the modem | | **Cannot update firmware \| 28674 Error** | **This is a network issue. The OTA Firmware Update could not be validated or was incomplete**. Ensure your device is as close as possible to the router. Check signal strength in **Diagnostics** | | | **Error opening an HTTP connection**. Check your modem or router settings. A VPN, Firewall or other setting may be blocking outgoing connections - this is a common reason for this error | | | Ensure you have a strong 2.4gHz WiFi signal (not just 5gHZ).
