This problem usually occurs when you set a restore height that is higher than the block height of the first incoming transaction to your wallet. To solve this issue, you will have to change the wallet restore height. Please read [this guide]({{site.baseurl}}/resources/user-guides/change-restore-height.html) for detailed instructions on how to do this.
Use the field `Seed offset passphrase` to enter your passphrase, if you have one. When you enter a passphrase, Monero GUI will use your mnemonic seed together with your passphrase to compute a new wallet.
You should restore your @wallet in the following situations: - You lost access to your wallet (you forgot its password, your wallet file is corrupted or your device stopped working/is lost).- You want to create a copy of your wallet on another device.
