Pending nonce {} is outside the owned reconciliation range {

Error message

Pending nonce {} is outside the owned reconciliation range {}..={next_nonce}

What it means

Rebroadcast verification guard: the chain's pending nonce for the signer lies outside the expected owned range between the prepared nonce and next_nonce, meaning another source submitted transactions with this wallet; the rebroadcast is aborted.

Solutions

1. Verify the pending transaction belongs to this wallet
2. Refresh the owned nonce range from the chain before retrying
