AkousaEADDRINUSEThe network address (IP + port) is already being used by another process.
Another process is already listening on the same port. This commonly occurs when restarting a server before the old process fully terminates, or when multiple instances try to use the same port.
Stop the other process using the port. Use a different port. Wait for the old process to release the port. Use SO_REUSEADDR socket option. Find the process: lsof -i :PORT or netstat -tulpn.
