------------------------------------
Summary: Guacd host set to 127.0.0.1 -
GuacamoleWebSocketTunnelEndpoint Connection to guacd timed out
Key: GUACAMOLE-1959
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1959
Project: Guacamole
Issue Type: Bug
Components: guacd
Affects Versions: 1.5.5
Reporter: Jason Mac
Just installed natively on Debian. When opening a connection, tomcat9 displays
the error that the connection to guacd timed out.
I know there is a lot of errors already online around this issue, but the port
is open and it is NOT using localhost, viewing the logs shows clearly it is
using 127.0.0.1

When placing guacd into debug mode via /etc/guacamole/guacd.conf there is ZERO
debug messages during the connection attempt.
Conducting a packet capture on loopback, there is an entire TCP connection
happening, about 13 packets, before the error occurs.
Clearly something else is going on, as the connection did not time out, the
pcap shows it connected just fine.
The RDP connection is open, and from a terminal on the guacamole server I can
easily netcat to the windows machine.
