I don't think you're using the correct header, here for the Guacamole
authentication token - you should be passing a header called
"Guacamole-Token" with the Guacamole authorization token. Guacamole does
not generally use the "Authorization" header.

Two issues, here:
* We've removed the ?token= parameter in recent versions in favor of a
model that prefers/uses a header, instead, so you should leave off the
token= part of this.
