This question already has an answer here:
An Monero GUI (Vo.14.0.0 (qt5.7.0) account was setup, a wallet name and password created and the 25 word mnemonic seed recorded. Commenced a synchronization and when thought completed after about four days, XMR coins sent to the account, but not ever received. When Monero.gui site opened, the balance is zero and a notice says that it is “waiting for daemon to start.” When an attempt is made to start it, a dropdown message says … “Daemon failed to start” … and "Please check your wallet log for errors. You can also try to start monerod manually.”
How can daemon be properly activated? How can sync completion be verified and account properly activated?
