DF fails on a local network, if internet connection goes away

OK - this seems to be related to my own topic

How can I avoid the DSP trys to reach out for the internet

Every once in a while (quite too often IMO), the DSP wants to connect to external addresses (e.g. github.com). (Especially, if I access the ‘Users’ menu-item.) How can I avoid that? I need the backend to work in a LAN w/o Internet-connection. It should be possible to switch these requests off.

But for me, this one is more serious (it also disallows me to work on apps while on a plane, or something).
