Connect for Chromebooks Log

Connect for Chromebooks provides a log of the user activity from the Chromebook it is installed on, namely which users have logged on, and the status of their login:

1. From the Chromebook, click the Connect for Chromebooks icon.

2. From the pop-up window, click Diagnostics.

Origin_Mismatch Error

If you are using Google verification with Connect for Chromebooks, you may find your users see this error in their Chrome browser when they click the red Google sign-in button.

This indicates the Smoothwall hostname does not match the one configured in the Google API console for the web application (Authorized JavaScript origins) — see Where do I get the Client ID and Client Secret from for Google authentication?

Ensure that the hostname configured is the Smoothwall appliance's fully qualified hostname, for example:

https://local.smoothwall.com:442

Tip: It should be noted that hostnames are case-sensitive so you must configure the Authorized JavaScript origins parameter to be exactly the same as the Smoothwall hostname.

Invalid_Client Error

If you are using Google verification with Connect for Chromebooks, you may find your users see this error in their Chrome browser when they click the red Google sign-in button.

This indicates that either the Client ID or Client Secret, or even both, that the Smoothwall is sending to Google for user verification purposes does not match those in the web application created in the Google API console — see Where do I get the Client ID and Client Secret from for Google authentication?

Log back into the Google API console, go to theCredentials page and copy the Client ID and Client Secret again.

Log back in the Smoothwall administration user interface, go to Services > Authentication > Google and re-enter the Client ID and Client Secret.

Unable to Determine a Proxy Server

Should Connect for Chromebooks be unable to determine a proxy server, or your network is configured for a transparent proxy method, an additional DNS entry should be added to your local DNS settings:

autodiscover.smoothwall.net mapped to the internal IP address of the Smoothwall.

This is because Connect for Chromebooks uses the above domain name when attempting to communicate directly with the Smoothwall in the absence of a proxy setup.

My Network uses a Transparent Proxy Method

If you network uses a transparent proxy method, you should add the DNS entry detailed above.
