Fix on macOS AnyConnect error: cannot confirm it is connected to your secure gateway. The local network may not be trustworthy. Please try another network

Open terminal and do the following (you will need administrator rights on your Mac)

cd /opt/cisco/AnyConnect

sudo nano AnyConnectLocalPolicy.xml

Then edit the field for ExcludeMacNativeCertStore to "true"

Quit AnyConnect and start it up again. 

You will now receive a certificate warning with the option to continue and, if available, install the certificate.
