App panics on restart before network is ready

[mhluongo]

Found this on Ubuntu 20.04 after waking up from a hibernate. As the network was reconnecting, the app shutdown and brought up a crash report dialog.

Seems like a quick fix is a back-off / retry, and longer-term you need an idea of connectivity in the app.
