Hello, I am trying to connect to the appstore from the modeler. When I am connecting to the appstore, the logfile show me the following error. System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at https://appstore.home.mendix.com/ws/AppStoreServiceMx6_1/ that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---> System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required. The proxysettings are working for the rest of modeler, but not for the appstore. Is there a solution for this problem? I already tried this solution: To work from behind a proxy server or firewall, you have to add the following lines to your modeler.exe.config. <system.net> <defaultproxy enabled="true" usedefaultcredentials="true"> <bypasslist> <add address="localhost"/> </bypasslist> <proxy usesystemdefault="True" proxyaddress="http://192.168.10.8:8080/" bypassonlocal="False"/> </defaultproxy> </system.net> Regards, Bas
