Answer 1

When you click on try it, what's the URL it invokes?
set proxy ports in workers nodes and see
Go to /repository/conf/tomcat/catalina-server.xml and set the proxy ports as follows
<Connector protocol="org.apache.coyote.http11.Http11NioProtocol"
port="9763"
proxyPort="8280"
<Connector protocol="org.apache.coyote.http11.Http11NioProtocol"
port="9443"
proxyPort="8243"
