Not able to access Apache Tomcat Server 9.0.73 remotely

Question

I have installed Apache Tomcat 9.0.73 on RHEL remote machine.

I followed the installation steps from this link - https://www.digitalocean.com/community/tutorials/install-tomcat-on-linux

Apache Tomcat Service is running properly, but I am not able to access it remotely. For example - http://<Remote_IP_Addr>:8080/ Tried accessing manger & host-manager profiles as well but facing the same issue.

Till now I have tried the following -

1. Allowed 8080 port

2. Bind the address to 0.0.0.0 in the server.xml

3. Added new role & user for manager-gui & admin-gui in tomcat-users.xml

4. Commented Valve tag in context.xml of manager & host-manager profiles. Referred ans from this link - https://serverfault.com/questions/796960/how-to-access-tomcat-manager-gui-from-another-machine

Let me know if this is the right way to access it remotely. I am facing this issue for quite some time.
