Users experience issues with Google Chrome Remote Desktop traffic through the ProxySG appliance.

Chrome Remote Desktop is a remote desktop software tool that allows a user to remotely control another computer using the Chromoting protocol. Both the Chrome Remote Desktop tool and the Chromoting protocol are developed by Google.
 

Install the following policy on the ProxySG appliance:

define condition HTTPPost 
http.method=(POST) 
end condition HTTPPost 

define condition chromelogin 
url.domain=accounts.google.com 
url.domain=www.googleapis.com 
end 

<Proxy> 
condition=chromelogin condition=HTTPPost Authenticate(no) 
url.domain=chromoting-client.talkgadget.google.com Authenticate(no) 

<Proxy> 
ALLOW url.regex="ssl://" 

Then, configure the firewall to allow access to the UDP port (which the appliance does not intercept):

chromoting-client.talkgadget.google.com 
kul06s11-in-f10.1e100.net 
kul06s06-in-f16.1e100.net 
sa-in-f127.1e100.net 

Note: The preceding is a sample URL only; you can find out from the Google Chrome Remote Desktop team if other URLs/FQDN should be allowed from the firewall for UDP access.
