Attention Mercenaries,

Many of you reported that you receive an error during playing CrossFire or when logging in similar to this:
Failed_to_connect_to_Host_Server.png

  • Please be aware that does not effect all of the players of a specific region or Internet Service Provider.
  • It is not an issue we can solve from our end, but we monitor the situation closely.
  • Most of the time the issue gets solved by itself but you can try a few steps of troubleshooting that might solve the issue for you.
  • Even if the issue returns after it was solved, you can try again to solve it.


1. Check the Firmware of your Router/Modem.
  • If the last update was a very long time ago, please check if you can get an update.
  • If you Firmware was updated very recently, you might have received a faulty update, and want to try to roll back the Firmware to a previous update.
  • For instruction to find this, please check the manual of your Router/Modem or check for a manual online.

2. Opening ports: In order to allow information from the internet or an online game to reach your computer, you might need to open a port through your Windows Firewall.
  • To open a specific port, use the following steps:

[LIST=1|INDENT=2]
[*]Click on the Windows Key + R on your keyboard
[*]In the Run window that will appear, type firewall.cpl and hit Enter
[*]Click on Advanced Settings on the left menu (You might need Administrative permission)
[*]You can either follow the instructions on the screen, or use the following guide: http://www.mytecbits.com/microsoft/windows/opening-port-in-windows-8-firewall
[*]You will need to open 6 different ports for CrossFire. The details for these ports are listed below:
[/LIST]
- Name: Crossfire1 – Port: 13008 – Protocol: TCP
- Name: Crossfire2 – Port: 13008 – Protocol: UDP
- Name: Xtrap1 – Port: 10009 – Protocol: TCP
- Name: Xtrap2 – Port: 16666 – Protocol: TCP
- Name: Xtrap3 – Port: 10009 – Protocol: UDP
- Name: Xtrap4 – Port: 16666 – Protocol: UDP
  • If you are using an internet router, most likely it will have a separate Firewall. Since there are many different manufacturers, we are unable to provide a one guide for all of them. Please consult with your router manufacturer’s guide, or visit http://portforward.com to find instructions of how to forward the above mentioned ports.
3. Flush and register DNS. Please try following instructions:
For Windows 7 or 8:

[LIST=1|INDENT=2]
[*]Hold down the Windows key and press R. (This will open the Run dialogue.)
[*]Type cmd and press Enter. (This will open a command prompt.)
[*]Type ipconfig /flushdns and press Enter.
[*]Type ipconfig /registerdns and press Enter.
[*]Type ipconfig /release and press Enter.
[*]Turn off your Modem/Router and wait 5 minutes
[*]Turn your Modem/Router back on, wait until it booted completely
[*]Back on your PC, type ipconfig /renew and press Enter.
[*]Type netsh winsock reset and press Enter.
[*]Reboot your computer.
[/LIST]
