Failed to Bind to port?

First off, I have tried the solution in the FAQ, didn't work. Here's the Error.

[INFO] Starting Minecraft Server version 1.3.1

[INFO] Loading properties

[INFO] Default game type: SURVIVAL

[INFO] Starting Minecraft server on -:25565

[WARNING] **** FAILED TO BIND TO PORT!

[WARNING] The exception was: Java.net.BindException: Address already in use: JVM_Bind

[WARNING] Perhaps a server is already running on that port?


Also for some reason my IPv4 Address is now different, I think my ISP changed it. I dunno if that has anything to do with it. If anyone can help me I would be so happy! Thanks!






EDIT: I notice everytime I try to run it I get a Crash report my OS Is Windows 7 Home Premium

It means that 25565 is already in use (so you can't forward your port on 25565).
Did you run your server before? If you start your server, and close the window (without typing "stop" in the console), that error happens.

The only way to fix it is to restart your computer.

 

your internal ip (IPv4) changes everytime you re start your computer unless if you static it
check out my guide to portforwarding

 

I ran this server for 2 1/2 months. I tried restarting my PC

Can I not fix it?

have you portforwarded though?

 

Yes.

I get an error log when I try to use STOP. In OP .

Alright something weird is happening, my server is running even though I haven't ran the RUN.bat???

you probly double clicked on the craftbukkit.jar
open task manager and close any java proccess. sometimes know as java.exe or javaw.exe

 

Tried that, still running?

 

what do u mean still running? can u c the black window (cmd) with bukkit in it

 

NO Only things that are running, Google Chrome, Skype, Steam. That's it! I went through the processess, Killed em, got onto MC and I still got onto my server!???

 

you need to leave the server ip blank in server properties

 

I did that.....

 

Listen i have the same problem but if you leave the ip blank on server properties you then cannot connect to your server

 

Alright for some reason the server just crashed, and now RUN.bat works, RESOLVED

 

If only that happened to me

 

It runs without it for me.

 

Hmm weird
-Some people have this port problem it needs to be fixed

 

It can't be fixed, nothing is broken
It's simply telling you the port is already being used, so simply use something else, or ensure your server hasn't crashed and gotten frozen, check to see if java.exe is running, if so, kill it!

When someone says to use task manager to close or kill a program(like jacklin213 said), it usually means the "Processes" tab.
For example to kill "java.exe":



Also do the same with "javaw.exe" if it's there.

 

Whenever you start your server (without the error), you have to type ' stop ' in the console. If you don't, and instead close the window (aka the red x), then your port will still run in the background. The only way to solve that (that I know of) is to restart your computer.

When you get the 'Failed to Bind to Port' error, then type stop, it will give an error. Just type stop again.

 

When it says failed to bind to port that's when u click x cause sometimes typing stop will give off more errors

 

some other program is already bound to the port

 

Solved that bit already....

 

I didnt read replies....

To check go to your router page>port

then it lists what is bound to what port
(portforwarding page)
(I don't know much about it, I vaguely remember from when I did this for a friend)

 

solved that too.....

 

ah i see, not only solved in the post but solved by you......

 

lol np ur just trying to help
