    Help, I had a hamachi server before but now hamachi stop working for me so i decided to buy minecraft and i did, i made new bukkit server but it doesnt work. Always when i try to run it it says
    Failed to bind port.

    I did added my external ip and 25565 port to my virtual server in my router..i tried it with simple port forward program but still doesnt work it says (in simpleportforward program) FAILED


    i checked my port if its open in some other websites and with PFportchecker but still doesnt work.



    I tried with server ip=<blank> it worked fine but my friends couldnt join.
    I tried with server ip=<ipv4> it worked fine but my friends couldnt join.


    Few days ago i port forwarded it sucessfuly until i changed some plugins and files in my server folder..I checked the planetminecraft "Verify Server Ownership" it worked...but now it doesnt.

    Removing the server-ip feild leaves it public, trust me.
    Ive run a server like this for two years. just set it to blank and start the server.

    In the file, the only reason the server-ip needs to be filled in is if the computer has two or more internal IP addresses (Which 95% + of computers don't).

    Leave it blank, the router automatically sends the players to the computer with the server.

    but what will my ip be?

    Your internal or External?
    All you need to worry about is your external (For others to connect), leave the server-ip blank, start the server, and give the players you external IP (and sometimes the port)

    your IP will be your IP, or do you think that bukkit changes your real IP address? :) The option only tells minecraft which IP to use, it uses *all* of them by default.

    That will give you the ip adress the users need to use to connect.

    Ok, so i tried with leaving the serverip blank, server was able to start but i cant connect with my external ip only with ipv4!

    Then you haven't port forwarded correctly, or have missed a step, have you opened the ports in your firewall?

    Error: I could not see your service on ********* on port (25565)
    Reason: Connection timed out

    Simple put, something is blocking incoming connections to the server.
    Do you/Have you;
    1) Have a 3rd party firewall/anti virus (AVG, Kaspersky, BitDefender)?
    2) Have a modem and router, or just a modem?
    3) Double checked the port forwarding is right/IP is right. You more than likely have a dynamic IP which causing your computers IP to change at times when it's turned on.

    1) i have AVAST but its offline..
    2) i have both
    3) i checked it and is all good..
    so what should i do?

    Just a thought, but maybe something has gone wrong when port forwarding between the modem and router. Try something like this;
    Internet > Modem (All ports open) > Router (Choose which ports are open) > Server

    If that makes sense...

    Also, do you have TeamViewer? It might make things a little easier to do.

    "Internet > Modem (All ports open) > Router (Choose which ports are open) > Server"

    Maybe it might be easier for me to take a look though it with TeamViewer, PM me the login details? (If you want)

    Hi I have the same problem I opened the port in my firewall and on it replied "Connection refused"

    Using hamachi for a public server isnt recommended, either get a server on 24/7 with port forwarding, buy hosting, Or Dont bother. Hamachi Hostin for big public servers aint good less you pay hamachi for more slots

    Add your internal ip to server ip in then wait 5 minutes start server again and only use stop in the console to stop server. Connect using external ip

    1)go to cmd and type in "ipconfig"
    2) go to IPv4 address and what ever it is, copy it.
    3)go to your and type the IP on the server-ip: line.
    4)run your server, and it should work!

    Hope this helps!

    i put my ipv4 address in the server properties but now when i attempt to start up bukkit, i says ''server cant keep up , did the system time change or is the system overloaded? plzz help. how do i fix this
  29. Offline


    it doesn't matter that much it just means alot is happenning on your server and it is too fast i think

    Ok, if you have a modem and router, try portforwarding a lower port (180) and then in change port to 180. When people join your server, the ip will be <external ip>:180 ex:
    Sometimes a router can't open high ports... Try, if not, I can't help you ;)
