Updater Problem

Since a few minutes i got a problem with my updater. Server is running everything is working fine i logged out and for some reason, my updater sais now, "Connection to the server could not be established".

I looked through my DB, and everything looks fine. So can anybody help me to fix my problem?

If you are running your own webserver be sure its started and the right url is written down in the Updater.exe.
