Problem: I see the error message ‘TransactionExpiredBlockheightExceeded’ and my Solana transaction is failing.
Cause: Too much time passed between the transaction being created and you signing it. The blockhash got too old in the meantime, and the transaction expired.
Solution: Try submitting the transaction again. If you’re using a hardware wallet to manage your Solana account, remember that you need to interact with the device (i.e. press buttons) to sign the transaction, so be ready to do this when prompted: you have approximately 60-90 seconds to review and approve the transaction after it has been created.
