Check for issues with TLS inspection

If TLS inspection isn't working verify that the hostname whitelist is working

- Boot up and sign in to your Chromebook or login as guest.

 - Use the keyboard shortcut Ctrl + Alt + T to open the Crosh terminal in your browser.

- Type:

network_diag --hosts

or, if you use a HTTP proxy:

network_diag --hosts --proxy

where is the hostname and port of your HTTP proxy.

The command will attempt a TLS connection to each of the hosts in the whitelist and report PASS / FAIL. If all hosts are not passing, check your firewall / proxy to confirm the host is properly whitelisted.

Sample command and output:

crosh> network_diag --hosts

checking PASS

checking PASS

checking PASS
