guacd connection refused from docker image
I used docker to deploy guacd, guacamole, and mysql. I thought I had
everything setup correctly. I'm able to bring up the web gui and
login, but when I try to connect I'm getting a connection refused in
the catalina log file as shown below. I even confirmed that guacd is
listening with the netstat commend at the bottom. I'm at a loss as to
how to investigate further whats stopping the guacamole client from
being able to connect to guacd. Can anyone offer any suggestions?

correct hostname field everything worked.
I wonder if the logging could be enhanced to say somewhere what
address its failing to connect to (either the proxy address or the
guacd address). If I had seen my RDP servers IP address as the guacd
server I would have immediately understood the problem.

I think we should also consider whether the proxy address, etc. could be
better displayed such that it's not so easily confused with the connection
parameters. I've made the same mistake myself several times.

Thanks for the great app guys!
