[UI5 Android app] cannot connect remotely

I have a Vera 2, so I use the old Vera app on my Android phone. It works fine locally, but when I try to connect remotely it fails.

I found this page, which mentions a way to get data from the Vera using fwd2.mios.com, but when I try to access [u]https://fwd2.mios.com/john/tokyo/10266/data_request?id=lu_sdata[/u] (data replaced, of course) I get “The requested URL /port_3480/data_request was not found on this server.”

Are these two related?
