org.freedesktop.libmbim.Error.Status.Failure: Failure

[Dan Williams]

Hi,

Could you run:

mmcli —set-logging=debug

And then retry the connection attempt?

Then grab the service logs and scrub them for information you don’t want public. You could also just send them to me privately.

The debug logs will show more information about why the connection fails.

Thanks,
Dan
