Verify Channel State: Ensure that the channels are active and not in a pending or closing state. Sometimes channel states can affect the balance being displayed.

In Umbrel:

Log into the Umbrel dashboard via a web browser.

Navigate to the Lightning wallet.

Look for the channels section, where you should see a list of your channels along with their status (e.g., active, pending, closing).

To list channels and their status in LND:

`lncli listchannels`

This will return a detailed list of channels along with their status and other information. If you're using c-lightning or another implementation, the command would be different, and you should refer to the specific documentation for that implementation.
