If this message pops up when you try to create an online game (a few people get this so this is my best attempt at helping :D )



Check that you have forwarded the port 54000 tcp/udp in your router settings.

If you do not know how to do this there are tutorials on the internet, try googling "port forwarding" or if you know what router you are using then google port forwarding for your router specifically :)

to access your router settings type your gateway address into your web browsers url bar

to find the gateway ip address (Windows Vista / 7):
-open start menu
-click control panel
-"open network and sharing center"
-under "View your active networks" find the network you are using
-next to the "Connections: " text look for the connection you are using and click it
-a window will pop up, click on the "Details" button
-look for IPv4 Default Gateway and that is your gateway ip address.
(take note of your IPv4 address too)

Generally the forwarding options are under some sort of "Networking" tabe or menu, some routers even label it under gaming and such but every router is slightly different and have their options in different places and call them different things.

you want to basically forward the port 54000 - 54000 tcp / udp to your computers IPv4 address which can be found in the same window as the gateway.

Typically, the port forwarding should look similar to this:



Then have your friends try to connect to your game.
Make sure you also try connecting via ip address in game, but note that your friends will need to type in your public ip address (which can be found by googling "what's my ip") followed by a colon ( : ) and then followed by the port number (54000) with no spaces in between.

example: "your public IP address":54000 , 180.216.01.010:54000
minus any quotation marks (180.216.01.010 is an example IP to show what it should look like)

Achoum created a faq generally explaining how it all works also:

Hope any of this helps :)

EDIT: if that link doesn't work then try copying and pasting this into the url bar of your browser

@Happystinger

Hi sorry i wasn't that clear before in the tutorial thanks for posting :)

When you forwarded the port to your IP address, which address did you use?
the private IP (that should look like this: 192.168.2.10) or the public IP address (and that one should look like this: 180.216.10.82)

you should forward the port to your private IP address (ex. 192.168.2.10)

but let me know if that doesn't work either.

For The Belgian users, use the url "192.168.1.1" (Bbox) to find the routeur settings. After that go to Advanced Settings and LAN Server to set your ports.

Another way to find your ip is write CMD in the search bar (start menu or windows+R) and write "ipconfig" in the black window and take the "IpV4" :)
