Problem:

When I try to submit a transaction using my hardware wallet, I see an error message.


Solution:

Please ensure that your hardware wallet’s firmware and app are up to date, and that your device is unlocked and ready.


Additionally, close any programs that might interfere with the connection between your Ledger/Trezor and your computer. This includes Ledger Live, Trezor Suite, antivirus software and browser add-ons. If you're using a Ledger, please make sure that the Cardano app is running and you see the prompt 'Waiting for commands'.


If that doesn’t fix the problem, try using a different browser.


Please also note that your device will fail to sign a transaction if the seed phrase or passphrase for your device is different from the one in use when you first paired your hardware wallet.
