Hi @chumanhhung235,

Only one process can listen on a specific port.
The message is clear: you already have a process using 3310.
You should stop this process before starting a new one.

thank you, how to stop this service by npm command?

Certainly just by closing the command window used to start the process.

If you can’t find anywhere this running service, you may find it by retrieving the process ID from the listening port.

For mac, for Linux, for windows
