Fix Minecraft 'Connection refused: no further information'

The error io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information means the address was reached but nothing was listening on that port. Usually the server is offline, the port is wrong or the firewall blocks it.

Checklist

1. Confirm the server is running and fully started.
2. Check the address and port you typed. Java default is 25565.
3. Check server.properties for server-port and make sure it matches.
4. Make sure the server is not bound to the wrong address. Leave server-ip blank unless you know why you set it.
5. On a home server, check port forwarding and firewall rules.
6. Try joining with localhost from the same machine to confirm the server itself works.

If localhost works but friends fail

The issue is networking: port forwarding, CGNAT, firewall or the wrong public IP.

Hosted servers

On a host, check the Console tab to see whether the server has started and what port it uses. On Tabi Cloud, use the address shown for your server.

Other messages

• Connection timed out is different and points to blocked traffic. See our timeout guide.

Common mistakes

• Using a local IP when friends are remote.
• Forgetting the port when it is not 25565.
• Server crashed or still starting.
• Trying a Bedrock address on Java.
