Common issues include: node not connecting to API, sync failures, high resource usage, and reward calculation problems. Most issues can be resolved by checking logs, verifying configuration, and ensuring stable internet connection.

If your node cannot connect to the Kasparex API, check: firewall settings, network connectivity, API endpoint configuration, and ensure the API is accessible from your location.

KREX Nodes should use minimal resources (0.2% CPU, 30-60MB RAM). If you see higher usage, check for multiple instances running, verify you're not running a full Kaspa node by mistake, and ensure no other heavy processes are running.
