Install Dynmap or BlueMap, set its web server port to an extra port from the Network tab, and open http://your-server-address:port in a browser to see a live map.

Install Geyser and Floodgate from the Plugins tab, add a port with Create Allocation in Network, set it as Geyser's Bedrock port, and Bedrock players can join your Java server.

Install Simple Voice Chat, add an extra port in the Network tab, and set that port in voicechat-server.properties. Every player also needs the mod on their game.

This error means the server, or a plugin, tried to use a port it doesn't own. Never change server-port yourself; the panel assigns it. Give plugins their own extra port from the Network tab.
