Some Servers not showing up

[Mameshiba 0]

Whenever I am looking for servers some of them only appear as a red 'x',sometimes up to 2/3 rd of the servers don't show up.

But when I select one of these server they will appear as normal and I can even join almost all of them and play on them without problems. Every now and then I get the 'connection failed' eventhough a friend could join it.

But its still very annoing if I want to play on a specific server because I have to click through every server manualy that did not load until I find the right one.
