Hard to say. Looks like after the super helpful "Failure" error, the
modem loses all the connectivity (signal 99->0) and (lte->unknown) and
gets unregistered from the network, which prevents further connection
attempts...

May be a network issue? Although you said it works under other OS, so not sure.
