If i try with World of Minecraft client, the login box appears, i press go. Them after a while it says "could not retrieve server list. going single player." Single Player Loads Fine. But in the Java CMD window it says Compass Initialized. attempting to use default windows plug-in.

Got Server: Generating level: planting..

 

Then says:

  

Java.net.connectexception: connection timed out: connect

It works perfectly fine at home. So it must be the server. There is only 1 proxy

 

Proxy.segfl.ifl.net > which can be overwritten with unfiltered.proxy.segfl.ifl.net

the port is 8080.

 

I had heard about people using:

 

java -Dhttp.proxyHost=hostIP -Dhttp.proxyPort=hostPort -Xmx800m -jar Minecraft.exe

 

But this is for Beta servers
