Symptoms

Errors in proxy-hydra.log:
407 Proxy Authentication Required
proxying failed java.net.SocketTimeoutException: Connect Timeout
Unable to pair connector with errors other than hostname verification.

Cause

This issue occurs due to to the incomplete proxy configuration related to the existing issue with Horizon Cloud Connector 1.5 and below.

Resolution

Adding “No Proxy For” (NonProxy_Hosts):

Version 1.4 and 1.5:

Open a Secure Shell (SSH) session to your deployed Horizon 7 Cloud Connector virtual appliance.

Save a backup copy of the /etc/systemd/system/hze-core.service file.

Open the original hze-core.service file for editing.

vi /etc/systemd/system/hze-core.service

Search for the property Environment="CATALINA_OPTS=. At the end of the property before ending double quotes, append the line -Dhttp.nonProxyHosts=’localhost|<HostNoProxy>’, where <HostNoProxy> is the fully qualified domain name (FQDN) of the no-proxy host that you want to configure for the Horizon 7 Cloud Connector virtual appliance and FQDN of Connection Server which will be used to pair with the appliance.

For example, if host-a.noproxy.example.com is the FQDN of the no-proxy host, modify the property so that it resembles the following:

Environment="CATALINA_OPTS= ...
...
-Dhttp.nonProxyHosts=’localhost|host-a.noproxy.example.com’"

Note: If you have multiple no-proxy hosts, you can specify wildcard entries using *. The following example shows the wildcard entries for hosts in thenoproxy.example.com domain:

Environment="CATALINA_OPTS= ...
...
-Dhttp.nonProxyHosts=’localhost|*.noproxy.example.com’"

Reload the daemon.

systemctl daemon-reload

Restart the hze-core service.

systemctl restart hze-core

Wait 1 minute for the hze-core service to complete its start-up sequence.

Verify that the hze-core service has started up by displaying the list of running containers.
docker ps
Verify that the output includes hze-core.

Version 1.3 & below:

Open a Secure Shell (SSH) session to your deployed Horizon 7 Cloud Connector virtual appliance.

Save a backup copy of the /etc/systemd/system/tomcat8.service file.

Open the original /etc/systemd/system/tomcat8.service file for editing.

Search for the property Environment='CATALINA_OPTS=-Djava.awt.headless=true'. Change existing starting and ending single quote to double quote. Now at the end of the property value before ending double quotes,-Dhttp.nonProxyHosts="localhost|<HostNoProxy>", where <HostNoProxy> is the fully qualified domain name (FQDN) of the no-proxy host that you want to configure for the Horizon 7 Cloud Connector virtual appliance and FQDN of Connection Server which will be used to pair with the appliance.

For example, if host-a.noproxy.example.com is the FQDN of the no-proxy host, modify the property so that it resembles the following:

Environment='JAVA_OPTS=-Djava.awt.headless=true'

-Dhttp.nonProxyHosts=’localhost|host-a.noproxy.example.com’"

Reload the daemon.
systemctl daemon-reload

Restart the tomcat8 service.
systemctl restart tomcat8
systemctl restart cccService
