Ledger Connected But Cannot Sign A Transaction can be frustrating when you need to complete an important cryptocurrency transfer. Several factors may prevent transaction approval, including an incorrect network, an outdated blockchain application, or a communication issue between your wallet and computer. First, ensure your Ledger device is unlocked and the appropriate cryptocurrency app is open. Check the connected wallet platform for error messages and install updates only from trusted official sources. Review the destination address, network, and transaction amount carefully before approving the request. If the problem persists, consult Ledger's official help center for reliable instructions.
