I am not entirely sure, but it seems to me that a licensed App is tied to a particular cloud node (or set of cloud nodes, like Acceptance/Production, etc.). So trying to run an App that is not tied to that cloud node within the node will not work. Maybe Mendix could chime in here and confirm if this is the case.
On a separate note, is there any reason you can't do your demo using a Sandbox deployment?
Hello Ralph, Please make sure that the node you are deploying is a licensed node and that you have the correct node security setting permissions. Also an attempt to deploy to another node could rule this and other troubleshooting thoughts out of the question. Please try this as well. If you have not done so already please submit a support ticket and we will look at the runtime connections, the specific cloud node connection, appnode-salmon-tr10000, etc., Keep note there is a similar ticket, so other developers may have experienced the same XMPP connection issue. https://forum.mendix.com/questions/6550/something-went-wrong-while-deploying-your-app-to-the-sandbox Thanks, Michael Schlosser
