This should not be the case.
Once the Cloud Client service is stopped and the PAc file is in place in the browser, it should show "Unable to connect to the Proxy server" and the user should not be able to browse anything on the machine,
Please check for a fresh installation and let me know the results.
Hi Mohit Groover:
You're right ... also thought to modify the proxy, but the service is stopped,
the Proxy continue working or would block all access to the Internet, but at
first stop after CloudClient Service, the message appears in the browser the
proxy server refuses connections, but continue to insist (opening and closing
the browser), this comes without any restriction.
This test is done in Windows 10, with 4 browsers, the most common:
Internet Explorer 11, Firefox, Chrome and Edge.
This video is reproducible if you have Teamvierwer Installed.
The video is 40Mb can dowload of my account of Dropbox:
Only after restart CloudClient Service, endpoint block Firefox and Chrome, if restart the system, endpoint block Internet Explorer and Edge.
