Awaiting Keycode Authorization

This has got to be one of the most irritating error messages you can get while trying to join a game. Especially when it's a LAN game!

After much troubleshooting, I am now able to fix this problem instantly. What is the solution? I can almost guarantee you it is because of one or more of the following:

  • You have multiple ethernet adapters enabled on your system
  • You have a VPN virtual adapter enabled (like a Hamachi adapter)
  • Your network stack order isn't right

I have a short video tutorial on how to correct these issues on the troubleshooting page. Just take a look at the 'Network Stack Order' video.

Also, I would assume at this point you would be attempting these fixes while your firewall is OFF. You may as well take that out of the equation for now. If this fix works, re-enable the firewall and see if it keeps working. If it does, great!

Now, I'm not sure of the exact cause, but I do know that if I leave Hamachi enabled on my system, this problem will ALWAYS occur. It also consistently happens if I set the network stack order wrong. I can guarantee that everytime I do one or both of these things, I get this error.

This fix has worked for me and all my friends when we have lan parties. I'm confident in saying that this will correct your issue as well.

**It is also possible that your host file has bad entries in it. More information is available in the troubleshooting section.**

 

What are the best settings for a LAN game?

  • Under Multiplayer Options, Make sure you have your connection set to 'LAN/Cable/DSL'.
  • Set PunkBuster to 'No'. This utility is more useful when playing online. Unless you really distrust your friends, just disable it

What are the best settings when setting up a LAN server?

  • Under Server Settings, set Pure to 'No'.
  • Also, set PunkBuster to 'No'.
  • Both of these settings assume you trust your friends. Both of these settings when set to 'Yes' check to see if anyone is cheating. However, they can also interfere with people's ability to play and stay connected. So if you trust your friends, just disable it. If they are cheating, go punch them in the face.
