PLEASE HELP'Perhaps a server is already running on that port'

Hello.
I have a very popular server but recently i loaded up my bukkit console and this error came up:
[WARNING] **** FAILED TO BIND TO PORT!
[WARNING] The exception was: java.net.BindException: Cannot assign requested address:JVM_BIND
[WARNING] Perhaps a server is already running on that port ?

So i have tried everything - Removing the ip from server.properties the console works fine but then i cnt get on my server it says: Connection : refused

*NOTE* I have portforward my bukkit and it was working untill today..*

I have searched on every site but still no answer
Please help
Many thanks -Adam

That really didnt solve my problem
Thanks anyway

 

So you've tried both in one minute?
1) Restarted your PC
2) Ended all java related processes

If so... nice fast pc you've got there.

Anyway, you could also try restarting your router.
Another option would be to clear your DNS cache. (although this should technically happen on reboot)

*Off to find command to list all ports being used....*

 

hmm yes tried it all
I had my server fully running for about 4 month and it suddenly decides to not load

I also have a fast computer..

Do you have something like a VPN or HideMyIP service active?

 

no.

 

Try opening a cmd prompt and type: netstat -b
Copy and paste the output, it might take a while.

If it's a lot paste it to: http://pastebin.com/

Of if it doesn't even fit in the CMD prompt, try
netstat -b > %USERPROFILE%\Desktop\ports.txt

It'll create a ports.txt file on your desktop once complete. (It'll stay on a blinking cursor for a while...)

 

it says its not recognised

Hmm this is annoying and btw i had a hamachi server before creating this bukkit would that effect anything?

What OS are you using?

Hamatchi... potentially but I doubt it... could try removing hamatchi though.

 

Well ive had this problem and i realized i was already running a server on that port. As in the server was already up. that might not be the problem you are having just trying to help

 

yeah i removed hamachi

How did you solve it?

They closed the server

So what OS? XP? Win7? MacOS?
If you're using a Windows machine, there is no reason the command netstat would not work.

 

windows 7

 

Well I had to restart my internet router and that seemed to fix it (not a reset a restart)

 

'Cannot find path specified'

Hmm thats 1 thing i havent tried
restarting my router...

Then yes, netstat as a command does exist.

1) click start.
2) type cmd in search.
3) right click on cmd then run as Administrator.
4) type netstat -b > %USERPROFILE%\Desktop\ports.txt
5) look on your desktop for ports.txt


EDIT: You need to stop replying in such small sentences so quickly... it's hard to keep up with helping you...

In what way is the path not found? (When does this error show?)

 

Its the system cannot find specified path Hmm are there anyspaces in there?

 

There are after netstat

Just type netstat, make sure you are running as admin and it should output something...

Btw netstat -b (when working) allows you to see what program or process is using what port.
So you'll find out what's using port 25565. (If it works )

 

hmm it comes up with Proto Local Address Foreign Address and state with a load of ips
when i type netstat -b

 

i also have same problem i have portforwarded but the computer acts like i didnt do anything
when i type mt external ip it dous not work only the ipv4 ip work which is lan
so annoying cant find help anywhere
