Doubt with synchronization

I have created a NEM node and I want to see the balance of an address, but it always appears at zero.

Is it because of the timing? how much the blockchain weighs and how much time it is downloaded on ssd drives with good network connection.

Hi, As you already noticed looks like your node is not synchronized. Please check endpoint http://<node_ip>:7890/chain/height to verify what block height it’s currently.
How much memory you have allocated in start script (Xmx option)?
