Update, see: https://bugzilla.gnome.org/show_bug.cgi?id=770504
Workaround with 1.4.0 is to add this section to
/etc/NetworkManager/NetworkManager.conf:
[device]
wifi.scan-rand-mac-address=no
With this setting and "systemctl restart NetworkManager.service", WiFi
authentication succeeds.
The upstream bug is a possible duplicate of:
https://bugzilla.gnome.org/show_bug.cgi?id=770456
I have supplied a log file and left it to the maintainers to decide.
Kind regards,
