ok I have change the adresse IP, now it's work but I think some thing goes wrong. I have no access to the APP :
"Download of appfeed failed.
Community Applications requires your server to have internet access. The most common cause of this failure is a failure to resolve DNS addresses. You can try and reset your modem and router to fix this issue, or set static DNS addresses (Settings - Network Settings) of 208.67.222.222 and 208.67.220.220 and try again.
Alternatively, there is also a chance that the server handling the application feed is temporarily down. See also this post for more information
