Hi @YurkoWasHere ,

I've got the same issue. I didn't read the docs and did a "blind shot" for a test-environment on a single VM. It'll work with at least 3 hosts.

The nginx-proxy is probably the reason for conflicts if "web", "agent" and/or "guac" are on the same host. Port 443 is already in use.

The 'inventory' file should look like this:

[web]
host1
[db]
host1
[agent]
host2
[guac]
host3

I still didn't read the docs. The issue may or may not be well documented.
