Issue:
Trying to install VNA 3.6.4 but it is failing with this error:

</html>Error installing plugin: /home/username/CA_VNA_Install/openstack-plugin-3.6.4-RELEASE.jar - 407. Please check the logs in /opt/CA/VNA/wildfly/standalone/log.
Environment:
CA VNA 3.6.x
Cause:
We use curl commands to install the plugins and curl will check and honor the environmental variable http_proxy if it is set. If the proxy wont allow us access, you will get this error.
To check if this variable is set:
env | grep http_proxy
 
Resolution:
Uninstall using /opt/CA/VNA/tools/bin/uninstall_vna.sh to clean up any remnants.

Clear the http_proxy variable while you are running the install.
export http_proxy=

after the install completes you can set the proxy back
export http_proxy=<your proxy>
