# Ledger errors: CLA\_NOT\_SUPPORTED and 0x6e01

{% hint style="info" %}
Generally these errors mean that you have not selected the correct asset. Example: If you are trying to connect the BTC chain to THORSwap you need to make sure that the BTC app is open on your Ledger and the device’s screen reads “app ready”. You also need to select BTC from the connection screen on app.thorswap.finance.
