I had attempted to install the recent version of Apache Tomcat (v9.0.70). The install went fine without issue or error. As I started the new Tomcat service, the Web Viewer logon page fails to load.
I had validated that the software installed.
I had validate the JAVA environmental variables.
I had checked the Java memory size
I had checked the local account.
All of which seemed fine. I had to roll back to 9.0.62 to get everything to work
Release : 12.1
Apache Tomcat 9.0.70
Needed permission to be able to create a work file under Tomcat 9.0.70
