Steps to Fix

Most of the Ledger Live issues can be resolve by updating Ledger Live application!

Download last version Ledger Live for:

**Download Ledger Live for Windows**
**Download Ledger Live for Android**
**Download Ledger Live for MAC OS**
Step 1: The main reason that this could be happening to you is that you are using an outdated Ethereum application. Whenever a new update comes out, it’s vital to install the latest version. So, if you haven’t downloaded a new version of the Ethereum application, then uninstall it and reinstall it on your Ledger Live.
Step 2: If the Ethereum application was not the problem, then you will want to make sure that if you are using a browser extension on Google chrome or other application that it is updated to the latest version.
Step 3: If the above steps did not work, then it is likely a windows ten security issue that needs to be bypassed. Move the popup to the side, but do NOT click cancel or the exit button. If you do this, then your device might freeze, and you will need to reconnect. Next, you will want to verify the transaction details and confirm the transaction.
