Also, I do see in Fernando's second screenshot the "Private" mode in the upper-right. It almost seems to me like something is blocking the images coming back from the web server to the browser, which could be one or more of a handful of things: * If the HTTP(S) is being proxied through either Apache or Nginx, this could be misconfigured in some way that is causing data to get lost or delayed in delivery, etc. If a proxy is in use, it's worth double-checking the proxy configuration to make sure that everything is pointed in the right place. In particular, if you're trying to change the path of Guacamole (Tomcat is exporting at /guacamole, but the proxy is exporting at /avocado), data could be lost. * Something network-related is interfering with the data being sent back. In particular I'm thinking of Layer7 firewalls, things that do Deep Packet Inspection (I've prior experience with Palo Alto-based firewalls), that might be stripping the data for some reason or another - data loss prevention, SSL inspection, etc. Fernando, could you pull up the browser developer console, specifically the network section, and see if there are any errors related to the images being passed back and forth? -Nick >
