Host 192.168.3.11 is actively refusing a connection on port 50000
- you might potentially be using the wrong IP address, but one that happens to be associated with an existing host
- your host might potentially have a firewall set up that is blocking outgoing connections to that host or that port
- the receiving host might not have anything configured for port 50000 and so is refusing connection to that port
- the receiving host might potentially have a firewall configuration that is blocking your access to the port
You are, however, reaching something that is actively refusing the connection. For example if you had configured a completely wrong IP address then there would be a delay while your system tried to send out a packet and your system waited for something to answer.
