I created a simple website with express, with chat feature using sockect.io. I was told that the conversations where droping all the time so I checked if I had any errors and I found this.

Error: listen EADDRINUSE :::3000

but after doing sudo lsof -iTCP -sTCP:LISTEN -P

I see only one app running on port 3000

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
systemd-r 699 systemd-resolve 13u IPv4 15747 0t0 TCP localhost:53 (LISTEN)
sshd 1006 root 3u IPv4 19017 0t0 TCP *:22 (LISTEN)

node\x20/ 3955 bruno 12u IPv6 227645 0t0 TCP *:3000 (LISTEN)

any idea how to get rid of that error?
