I made a server and used my IPv4 address for the IP. I decided to scratch that server and make a Bukkit server so I can use plugins. I tried to use my IPv4 address which I used for my other server but I keep getting the message [17:31:15 WARN]: ****FAILED TO BIND TO PORT!

Is there any thing I can do to get a new address to use or is there a way to delete the old server? Do I need to use a different computer? Please help! I've don't know how to fix this problem. If you have any suggestions please tell me and I'll give it a try.

  • What do you mean by "delete the old server"? As long as you don't run minecraft_server.xyz.jar there is no server. Make sure the other server is shut down, using either the /stop command or by killing all java/javaw processes. – MrLemon May 28 '14 at 8:34

Go to your server.properties and make sure "server.ip=" is empty.


Make sure the port you are trying to use for the server isn't being used elsewhere.

  • I remember doing that on my other server and I did it to mine a while back but it still doesn't work. – Snoflake4101 May 27 '14 at 23:17
  • So your still having the problem? – Caleb May 28 '14 at 0:10
  • Yes, do I have to use a different computer? Or is there another IP I can use? – Snoflake4101 May 28 '14 at 0:26
  • You can use the same computer, your IP will always be the same. Click here to find out your public IP, this is what you use to join the server. – Caleb May 28 '14 at 2:30
  • if you want to run two servers, on the other hand, you need to change the port -> find this line in the server.properties server-port=25565 and change it to a different number like 25566 – Lorenzo Boccaccia May 28 '14 at 21:29


  1. Open "Activity Monitor"
  2. Search "Java"
  3. Force Quit "Java"
  4. Start Server

This usually fixes the issue. Hope it helps for you.
