We have a websocket setup on an internal network 192.16.1.x IP addresses.  The server is running CF 2016 Updated to the latest patch as of this post.  We have a controller/publisher that was being run from an iPad and listeners/subscriber computers.  A user clicks through the site on the iPad and the displays update.  This worked until a week ago.

Attempting to run Chrome on the server and open the controller URL using the 192.168.1.10:8500 URL (using ColdFusion’s internal web server for simplicity) never updates the displays.  If I call the same URL changing to the local IP, 127.0.0.1:8500 then all of the displays/subscribers get their updates.

I opened several Chrome browsers on the server itself pointing one to the controller and the others to the same URLs as the displays would use, i.e. 

192.168.1.10:8500/index.cfm?mychannel=channel1, 

192.168.1.10:8500/index.cfm?mychannel=channel2, 

192.168.1.10:8500/index.cfm?mychannel=channel3

Calling the servers IP address will not update any subscribers.  No failure messages logged.  If I hit 127.0.0.1:8500, it will update all of the displays and even the Chrome browser windows I have open on the same server.

Running on Windows 2012R2, firewall is disabled.  Any thoughts or suggestions?
