Q: (Installation - Step 1) I am unable to download the .mobileconfig file. I can only see a page like this:

A: Your browser has opened the .mobileconfig file instead of downloading it. You can right click anywhere on that page and click "save as" to download the file.

Q: (How to connect - Step 3) After connected to VPN, I cannot access the sites that I normally have access to (e.g. Baidu), but I can access sites such as LEARN now. When connecting using Chrome, it shows the error ERR_TUNNEL_CONNECTION_FAILED

A: It is likely that the PAC file was not read properly due to some of your proxy server settings, especially if you have used other VPN services before on your computer. You could follow this guide to change the proxy server settings: 

The service is meant to be used  only for learning technologies in your courses  (such as LEARN, Crowdmark, PebblePad, Bongo), and only those applications are enabled through this solution. It does not lift restrictions on resources that are not generally available to you. Therefore, if you are trying to access sites such as Google & YouTube, you will get this error as we do not provide proxy for those.
