ResEl Secure wifi problem?

[Matthew Vernon <matthew@debian.org>]

Hi,

I've arrived in building I14, and registered via the ResEl Inscription 
SSID; but when I try and connect to ResEl Secure, nmcli says:

Error: Failed to add/activate new connection: Failed to determine AP 
security information

Is this a known issue? If so, what's the fix, please?

Thanks,

Matthew
