Hi Tom,
try vmconnect instead of nla for security. See
https://issues.apache.org/jira/browse/GUACAMOLE-952.

Hi Nick,
Deployed the war file on a test machine and unfortunately it still does not
work. I receive error
The remote desktop server is currently unreachable. If the problem persists,
please notify your system administrator, or check your system logs.
If I check syslog I see:

Connecting to regular RDP servers works without a hitch (even the Hyper-V host
for the guest I am trying to connect to). Relevant settings:
<connection name="VMConnect RDP (Win10)">
<protocol>rdp</protocol>
<param name="hostname">hyper-vhost.local</param>
<param name="port">2179</param>
<param name="ignore-cert">true</param>
<param name="security">nla</param>
<param name="ignore-cert">true</param>
<param name="username">connect-user</param>
<param name="password">Pwd1234</param>
<param name="domain">AD</param>
<param
name="preconnection-blob">970e1fcf-e920-4042-8774-4602c2f831fb</param>
</connection>
<connection name="Hyper-V RDP (Win2019)">
<protocol>rdp</protocol>
<param name="hostname"> hyper-vhost.local </param>
<param name="port">3389</param>
<param name="ignore-cert">true</param>
<param name="security">nla</param>
<param name="ignore-cert">true</param>
<param name="username">connect-user</param>
<param name="password">Pwd1234</param>
</connection>
All info including hostname, username, password and preconnection-blob work
with Guacamole 1.0.0. (on Ubuntu 18.04), connecting to hyper-vhost.local with
‘regular’ RDP works so it does not appear to be a network issue:
Checking guacd reveales it is indeed the 1.2.0 version:
May 08 06:16:55 guapo guacd[19318]: Guacamole proxy daemon (guacd) version
1.2.0 started
Any pointers and/or help would be greatly appreciated.
Kind regards,
Tom Daniels

Hi Nick,
Thanks so much for your swift reply; using openjdk-8 did the trick. Will roll
out the 1.2.0 build during off hours and will let you know if everything is
working as expected!
Kind regards,

Hi Nick,
Thanks so much for you reply. I will be happy with a working solution ;-)
For the last week I have been fruitlessly trying to compile the git version of
guacamole-client using maven.
With openjdk-13 or openjdk-14 installed I receive this error when running nvm
-X package
error: Source option 6 is no longer supported. Use 7 or later.
With openjdk-11 installed I receive this error
Exit code: 1 - javadoc: error - The code being documented uses modules but the
packages defined in http://docs.oracle.com/javase/6/docs/api/ are in the
unnamed module.
which supposedly is fixed in 11.0.8 and higher;
https://bugs.openjdk.java.net/browse/JDK-8212233 which will release in July.
Yeah, if you have an option to use JDK8, I would use that, instead. 11
*should* work, but there may be a Maven issue that blocks that. 8 works
consistently.
