If the wallet displays: "Sending failed: an error occurred" it means:
that you do not use the right application on your Ledger Nano S or Ledger Blue. Maybe you did not install it from the Ledger Manager. Please refer to this guide.
For example, it can happen if you use the Bitcoin application on your Ledger device while you were on the Bitcoin Cash application.
that something went wrong when synchronising your information. Please read the wallet on your computer by clicking on Settings > Tools > rRset application data. Now you can try again.
- that servers or the blockchain network are temporarily down or overloaded. Please try again later.
that the (amount + fees) > your total balance. Make sure that the amount you want to send added to the set fees is equal or inferior to your total balance.
- that there is an unconfirmed transaction in your wallet. You need to wait until this transaction is confirmed or rejected, Ledger can not take action in this process.
that you did not confirm the transaction. When you try to make a transaction, the Nano S displays the message "Confirm transaction" with a cross on the left and a check icon (✓) on the right. After verifying that the receiving address is correct, you can press on the check icon button.
|This verification step is the way to manually sign and authenticate your transaction. Here, you don't have to press both buttons, but only the right button above the check icon (or the left button if you want to cancel). If you press both buttons, the sending fails as it is considered as unconfirmed.|
