uncaughtException:Error: listen EADDRINUSE: address already in use :::3001

hi,

When I start the node.js server I get the following error:

uncaughtException:Error: listen EADDRINUSE: address already in use :::3001

I am not using 3001 elsewhere.

The following error also occurs when using cluster or cluster of pm2.

uncaughtException:Error: bind EADDRINUSE null:3001

I don’t know why.

I need your help desperately.

Environment : Node.js , AlpineLinux
