Answer

Connecting to the server

Java 8 - AccessControlException/SocketPermission

Due to new security 'enhancements', Java 8 is no longer able to connect to our servers in sandboxed mode. On the play (lobby launch) page, select launch option 'full-permissions'.

Client/Server version mismatch

The lobby has a newer version than your applet. Normally, when you restart your browser or your pc the newest version is automatically downloaded. If this is not the case, you can try clearing your internet cache/temp internet files and Clearing Java cache.

Connection refused

If you get a message like:

  • Connection refused: connect
  • Socket not connected: connect
  • Server not responding.

and you are sure the lobby is not shutdown or jammed (because this could cause the same message) then:

  • Your anti virus software blocks traffic between you and the server, or
  • You are behind a firewall or router that blocks the required network ports.

In both cases (if you have access to it) the solution is opening the following TCP ports for outgoing traffic:

Xplorers Ranking C&K 2TCP 1982
Xplorers Ranking Basic 1TCP 1983

Toulouse NonRankingTCP 1993 & 1994

MatchTCP 1973 & 1974
RoadBlockTCP 1975 & 1976
Some public computers (libabry, university, at work) are not able to connect to a server on anything else then port 80 (standard port). Usually you won't be able to change that.

Testing your connection to a port on our servers

Use telnet to test your connection to our servers without interference of your webbrowser or Java, open a command prompt:
Start->Run: CMD [enter] and type 'telnet games.asobrain.com 1980' (or replace 1980 with the lobby of your choice).

Type telnet games.asobrain.com 80 to test your connection

If you get the output below, telnet is not installed on your system. Since Windows 7, telnet is no longer installed by default. You can install it by going to 'Programs and Features' in your Windows Control Panel and select 'Turn Windows features on or off'. Check the 'Telnet Client' and continue.

Telnet is not installed

If you get the output below you are not able to connect to our servers on the specified port (or our servers are down). Your problem is probably not related to your webbrowser or Java but to your router/firewall/internet connection.

If you get the output below you are able to connect to our servers on the specified port. If you are still unable to enter the lobby, your problem is not your router/firewall/internet connection but probably related to security settings in your webbrowser or Java installation.
