Masterserver does not show any server??

[Anticamp05]

Read the documentation, and this is a guide to servers. Make sure you follow the guides, and your server will be working properly.

EDIT: The Idiot's Guide is outdated, but I'm sure it still works.

i already read it but it still doesnt give me answer, by the way i was play it online 1 hours ago then suddenly when i disconect and try to reconnect it again the masterserver wont show up any server, i try evrything rebooting and still, does this was happen to other player??
