Connection Refused

Players get 'Connection refused' when their client cannot establish a connection to the server at all. This is different from a timeout or a DNS error: the address resolved, but nothing accepted the connection on the other end.

O que significa este erro?
'Connection refused' means the client reached the target host but no service answered on that port. Either the server is not running, it is listening on a different IP/port, or a firewall / missing port-forward is blocking the connection. 
java.net.ConnectException: Connection refused: no further information
Causas mais comuns
  • The server is not actually running.
  • Wrong IP address or port used by the player.
  • The port is not forwarded on the router.
  • A firewall blocking the port.
  • The server bound to localhost / a different interface than expected.
Como diagnosticar
  1. Confirm the server is up and listening ('ss -tulpn | grep 25565').
  2. Verify the IP and port the player is using.
  3. Test locally on the host to rule out the server itself.
  4. Check router port-forwarding and the firewall rules.
Correções recomendadas
  • Start / confirm the server
    Make sure the server is running and listening on the expected port.
  • Forward the port
    Forward TCP 25565 (or your port) on the router to the host machine.
  • Open the firewall
    Allow the port through the host and any cloud/provider firewall.
  • Check the bind address
    Ensure server-ip is blank (all interfaces) unless you intend a specific bind.

Perguntas frequentes

Refused means nothing is listening on the port. A timeout means the connection attempt got no reply at all (often a firewall dropping packets).

Then the server is fine, the issue is port-forwarding or a firewall between the player and the host.

TCP 25565 by default, or whatever server-port you set, to the host's local IP.
