Hi All,   I enabled TLS for NIFI web UI ( CDF ) , while services are running fine on cluster I'm unable to access NIFI web UI from my browser. Below are the steps I followed please suggest what might be causing issue ?   I repeated below steps for all the machines in my nifi cluster   1. Received signed host certificate from IT team ( <hostname>.pem ) , also rootca (root.pem) 2. Copy the JDK cacerts file to jssecacerts as follows:     sudo cp $JAVA_HOME/jre/lib/security/cacerts $JAVA_HOME/jre/lib/security/jssecacerts     3. import rootca cert into JKS store     sudo $JAVA_HOME/bin/keytool -importcert -alias rootca -keystore $JAVA_HOME/jre/lib/security/jssecacerts -file /opt/cloudera/security/pki/root.pem     4. Created JKS and imported host certificate in keystore.     $JAVA_HOME/bin/keytool -genkeypair -alias $(hostname -f) -keyalg RSA -keystore /opt/cloudera/security/pki/$(hostname -f).jks -keysize 2048 -dname "CN=$(hostname -f),OU=Engineering,O=Cloudera,L=Singapore,ST=Singapore,C=Singapore" -ext san=dns:$(hostname -f) sudo $JAVA_HOME/bin/keytool -importcert -alias $(hostname -f) -file /opt/cloudera/security/pki/$(hostname -f).pem -keystore /opt/cloudera/security/pki/$(hostname -f).jks     5. creating symlinks     sudo ln -s /opt/cloudera/security/pki/$(hostname -f).pem /opt/cloudera/security/pki/agent.pem sudo ln -s /opt/cloudera/security/pki/$(hostname -f).jks /opt/cloudera/security/pki/server.jks     6.
