Solve a synchronization error in Ledger Live

A synchronization error may occur in Ledger Live when there is or has been a temporary problem with Ledger's blockchain explorers or network. 

This problem can be solved by first updating to the latest version of Ledger Live.

Once everything is updated, clear the cache after the service has been restored. To clear your cache, simply go to the Settings menu -> Help -> Clear Cache.

Ledger's blockchain explorers are full nodes that validate, store, and index all the transactions on various blockchain networks. Ledger Live calculates the balance for each of your accounts by requesting the transaction history from the blockchain explorers. 

  Are your coins still safe?

Yes, your coins remain secure. During a synchronization error, Ledger Live cannot be used to manage your coins like sending, checking the correct balance, or staking. Your coins are safe on the blockchain and your private keys remain securely stored on your Ledger device. During the outage, you can use the third-party wallet of the troubled asset

Still not solved?

    • Please rest assured, your crypto assets stay safe during a temporary outage of Ledger's blockchain explorer.
    • Your coins are stored on the blockchain network and the private keys providing access to your coins remain secure on your Ledger device.
    • You can always use an external wallet with your Ledger device. Check our list of supported crypto assets. For instance, you can use Electrum for Bitcoin or MyEtherWallet for Ethereum.

*Please note: updating firmware and apps in "My Ledger" isn't necessary to fix a sync error in Ledger Live.
