# Constructing Add Hotspot Transaction

## Helium App shows error constructing the add hotspot transaction when registering the Hotspot

### Troubleshooting Steps

1. If you register your hotspot right after you connect Ethernet or Wi-Fi, you will see this error since the OTA (over-the-air updates) is running or the blocks have not been fully synced yet.
2. Please leave your hotspot connected to Ethernet or Wifi for at least 30 mins to wait for it to finish the firmware OTA and the syncing process of blocks. After that, please long press the button for 6-10s to enter configuration mode and then try to register again.
3. Check the firmware version after completed using diagnostics or the SenseCAP Dashboard to make sure it is up to date.
   * **Note:** If the firmware of your hotspot cannot update to the newest version, then it is suggested to change the network your device using to another network, such as your mobile phone hotspot, and then follow the second step mentioned above.
   * **Note:** If the blocks cannot be fully synced by the device itself after the firmware OTA is finished, then it is suggested to reset blocks in the local console, and the instructions of which you can find by clicking [here](https://docs.sensecapmx.com/m1/local-console/how-to-reset-blocks).
