Minecraft-troubleshooting:Failed to bind to port
Console error: Failed to bind to port.
This error is caused by a mis-configured server.properties file.
To fix this error follow these simple steps, and you will be up and running in no time.
Step 1. Enter the gamepanel, and enter the game services afterwards. You should now be able to stop the server, which you need to do if you have not already.
Step 2. Click the configuration files tab, and locate the server.properties file. Usually its at the very top of the page.
Step 3. Press the Configuration Editor and edit the variables to fit your needs, like the server motd, pvp, whitelist etc.
