Ledger Connected But Cannot Sign A Transaction is a common issue users may encounter while managing cryptocurrency transactions. Even when a Ledger hardware wallet connects successfully, signing may fail because of outdated firmware, an incompatible application, incorrect network settings, or a connection interruption. Start by checking your Ledger device, updating Ledger Live, and confirming that the correct blockchain app is open. Review the transaction details carefully before approving anything. Never share your recovery phrase or private keys with anyone. If the issue continues, consult official Ledger support for safe troubleshooting steps and additional guidance.
