I have been successfully able to use Chrome Remote Desktop to access other computers when not behind a firewall/proxy server.
As soon as I try to use Chrome Remote Desktop when behind a firewall/proxy server. It can't connect. Do certain ports/services need to be opened/enabled for it to work?

Chrome's support page suggests you need the ports for https (443) and xmpp/jabber (5222) open. It also suggests that if nat traversal is disallowed on the firewall, chrome remote won't work. There's also a few more troubleshooting suggestions on the official google faq for chrome remote - the error messages might be informative, if you have any.
