i disabled firewall on server pc long ago, , did forward ports on router. tried portscanners , detect service on port, client fails reach again , again.

solved! i'm not networking seems impossible connect if both server , client on same router. tried connecting distant client , worked.

econnrefused means connection attempted , remote host answered nobody's listening on port. mean several things:

  1. is ip? ifconfig/ipconfig (hint: not whatismyip.com say)?
  2. does java server listen on interfaces? same port on localhost open , closed on other interfaces. check bind addess on server.
  3. try telnet + tcpdump, show packets go correct address?

and these start.
