How to fix the "Connection Refused" error on a Java server¶

The message "Connection Refused: getsockopt" usually appears when the Minecraft client cannot reach the server. On a NexusCloud Java server, the most common cause is that the client has not combined the server address with the port.

Steps¶

1. Open the NexusCloud panel and copy your server's Address/IP and Port.
2. Combine them into the ip:port format, for example hu-tao.nexuscloud.id:12345, then copy it.
3. Open Minecraft, go to the Servers list, then Edit your server.
4. Remove the old address, then paste the ip:port string you copied.
5. Click Done, then try to join again.

Notes¶

• The port used in the client must match the port shown in the panel exactly. If the panel shows 12345, enter hu-tao.nexuscloud.id:12345, not just 12345.
• If it still fails, make sure the server is online in the panel and that no firewall is blocking the connection from the player's side.
