Resolving Synchronization Errors on Ledger

A synchronization error occurs in Ledger Live when there is a temporary issue communicating with Ledger’s Ethereum blockchain explorers or validators. This prevents Ledger Live from getting an accurate balance or transaction history for your Ethereum account.

Symptoms of Synchronization Error

Here are some symptoms you may experience during a synchronization error for Ethereum in Ledger Live:

  • Inaccurate or missing ETH balance
  • Missing or failed Ethereum transactions
  • Error messages like:
    • Synchronization error
    • API HTTP 403
    • API HTTP 503
    • API HTTP 500
    • API HTTP 400

Are My ETH Coins Safe?

Yes, your ETH remains completely safe during a synchronization error. Your coins live on the Ethereum blockchain, while your private keys are securely stored on your Ledger device.

Ledger Live is simply unable to communicate with the blockchain to get updated transaction data. But you can still access your coins by using your Ledger device with a third-party wallet like MyEtherWallet.

How to Resolve Synchronization Errors

Here are the main troubleshooting steps to resolve Ethereum synchronization errors in Ledger Live:

1. Update Ledger Live

Make sure you’re running the latest version of Ledger Live on your desktop or mobile device. New versions often contain fixes for synchronization issues.

2. Update Ledger Firmware

Update your Ledger device’s firmware to the latest version available. This ensures compatibility with the newest Ledger Live software.

Go to the Manager in Ledger Live. Connect your device and install any available firmware update.

3. Update the Ethereum App

Make sure the Ethereum app on your Ledger is fully updated to the latest version. Go to Manager, find Ethereum in the list of apps, and update if available.

4. Check Service Status

Check status.ledger.com or @Ledger Support on Twitter to see if there are any known issues with Ethereum services.

5. Clear Cache

If services have been restored but you still have synchronization errors, try clearing the cache in Ledger Live:

  1. Go to Settings (gear icon)
  2. Go to the Help tab
  3. Click Clear Cache
  4. Confirm clearing the cache

This clears out any corrupted data that could be causing synchronization problems.

6. Synchronize Again

Try manually synchronizing your Ethereum account again in Ledger Live. In the Accounts tab, click the circular sync icon next to your Ethereum account.

If it works – great! Ledger Live should now display the right balance and transaction history again.

If not, don’t worry. Your coins remain secure on the blockchain. Keep an eye on Ledger’s service status pages for updates.

Accessing Coins During Synchronization Errors

Even during synchronization errors, you can still access your Ethereum coins safely using your Ledger device.

For example, you can connect your Ledger hardware wallet to MyEtherWallet. This allows you to view balances and broadcast transactions without Ledger Live.

  1. Go to www.myetherwallet.com
  2. Click the Hardware wallet button
  3. Select Ledger and connect your device
  4. Access your Ethereum account on MyEtherWallet

So your coins remain under your control through your Ledger private keys. You just lose some of the convenience of Ledger Live until synchronization is restored.

Preventing Future Synchronization Errors

To reduce synchronization errors in the future:

  • Always keep Ledger Live updated
  • Always keep your Ledger firmware updated
  • Follow @Ledger_Support on Twitter for service updates
  • Consider running an Ethereum validator node for maximum uptime

Conclusion

Synchronization errors can temporarily impact the performance of Ledger Live but do not affect the underlying security of your Ethereum coins. Follow the troubleshooting steps above or use a third-party wallet as a workaround. Keep firmware and software updated to prevent issues in the future.
