AJP connection fails

I have two CentOS 7. On one I have Open JDK 11 & Tomcat 9.0.43. The AJP connection setting is like below

    <Connector protocol="AJP/1.3"
           secretRequired="false" 
           address="::1"
           port="8009"
           connectionTimeout="10000"
           keepAliveTimeout="10000"
           redirectPort="8443" />

Added host entry in tomcat server.xml like below

<Host name="ptm" appbase="webapps"
        unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">

        <Valve className="org.apache.catalina.valves.AccessLogValve"
                 directory="logs"  prefix="resumesite_log." suffix=".txt"
                 pattern="common"/> 
        <Context path="/myapp" docBase="/pathtowebapps/webapps/ptm" debug="0" reloadable="true"/>

Firewall is disabled on both servers.

Proxy configuration is like below on apache 2.4

ProxyPass "/myapp" "ajp://<tomcatIP>:8009/myapp"
ProxyPassReverse "/myapp" "http://<tomcatIP>:8080/myapp"

I am able to connect to port 8080 via telnet but on port 8009 I am getting Connection refused.

Tomcat is listening on 8009, checked that with lsof -i -P -n

java       747     root   43u  IPv6 465743      0t0  TCP *:8080 (LISTEN)
java       747     root   49u  IPv6 465747      0t0  TCP [::1]:8009 (LISTEN)
java       747     root   62u  IPv6 466199      0t0  TCP 127.0.0.1:8005 (LISTEN)

java -version

openjdk version "11.0.10" 2021-01-19 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.10+9-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.10+9-LTS, mixed mode, sharing)

All ports are open from both machines.

Thanks for your help and support in advance.

Found the solution. Change the address to 0.0.0.0. That will do the trick.

address="0.0.0.0"

<Connector protocol="AJP/1.3"
           secretRequired="false" 
           address="0.0.0.0"
           port="8009"
           connectionTimeout="10000"
           keepAliveTimeout="10000"
           redirectPort="8443" />
