How can I make my Mashup accessible from extern Browsers?
I allowed http and anonymus users. You have to define a rule "user is anonymus". The IDs missing Errors are showing, if you trying to getApp() with a not existing ID.
You probably need to put in place an authentica strategy. When you try to connect from within your domain, Windows os is in charge to pass your credentials to the maschup therefore Qlik Sense, but when you try to access to the same page from outside your domain you are no longer authenticated, that's why the Qlik Sense Object are not reachable.
