So proprietary Broadcom wl driver, which gives you:

Oct 21 13:34:32 toaster wpa_supplicant[932]: wlp3s0: WPA: Failed to set
PTK to the driver (alg=3 keylen=16 bssid=34:97:f6:06:26:88)

This is most likely a driver problem.  The driver is refusing to accept
the WPA key that the supplicant is trying to give it, and that's what's
causing the disconnect.  To the supplicant and NM, this looks like the
key is actually wrong.  While the supplicant could handle this better
and notice that the failure to install the PTK is not actually the key
being wrong but the driver falling over, the driver really shouldn't do
that...
