Sounds like you're giving your friends the wrong address. Make sure you're giving your friends your public IP address instead of your private one. Private IPs can only be used in the network you're connected, which is likely why your brother can connect and your friends can't.
If you've set up port forwarding but your friend can't connect to your 1.14.4 Bukkit server, check the following:
Ensure your external IP address is correct.
Double-check the server's firewall settings to allow connections.
Verify that your friend is using the correct IP and port to connect.
Ensure your friend is not blocked by any server-specific plugins or settings.
Test by having your friend connect to your external IP address, not the internal one.
If the issue persists, there might be network or firewall issues on your friend's end, and they should investigate their connection settings and security software. For more information, click here.
