Chrome Remote Desktop cannot connect after changing server OS

We had been using Windows SBS 2003 as our network OS.  We recently purchased a new Dell server computer and also updated the OS to Windows Server 2012.  I'm supposing my problem is related to that due to the timing of it.  I use Chrome Remote Desktop from one of the client computers (I'll call it computer A) to access my personal computer at home and other computers.  Now, when I go into CRD and select it, or any other computer on my list for remote access, I get the message ... An unexpected error has occurred. Please report this problem to the developers.  I just set up CRD on another of the clients in this network (I'll call it computer B).  When I try to connect from A to B, I get the same message.  This error has been reported on several forums, but none of the possible solutions I've seen so far have helped in my case.  When I try to connect from B to A or from B to the outside computer, It just says, ... Connecting ... and nothing happens. Is it in fact a Windows 2012 issue?  Or an issue involved with transferring my client from the old server to the new?

It sounds more like a networking issue to me. The ports may now be blocked further up the chain.

I think it is a networking issue.  I understand that I need to have ports 443 and 5222  open.  I have access to the management of the network.  How can I ensure that these two ports are open?  I ran ...  netstat -ab | more.  I do not see either of those ports listed. But maybe I need to use a utility in Windows Server 2012 to open these ports.  How can I do that?

control panel | advanced firewall

I my client computer I had tried Firewall > Advanced Settings > Inbound Rules.  There I created a new rule to open ports 443 and 5222.  Even after rebooting the problem persists.  What do I try next?
