Installing Tomcat9.0.86 with thingworx 9.4.4 - Manual Installation - Linux Ubuntu 22.04.3 LTS

Hello, I am struggling with a fresh install of thingworx 9.4.4. More so I am struggling to get the tomcat service to start. It is consistently comming up with the error: ubuntu systemd[1]: tomcat9.0.service: Killing process xxxx (n/a) with signal SIGKILL.

I have made sure that the permissions on the PID file location belongs to the tomcat9.0 user.

I have followed the guide: Install Java, Apache Tomcat, and ThingWorx (ptc.com)
I have installed java -version- openjdk version "11.0.21" 2023-10-17.
I have installed tomcat9.0.86.
For now, I have just used the self-signed certificate for simplicity and will change over once I have the service working.

From the guide I made sure to do the following:
Edit AUTHBIND properties to allow Tomcat to bind to ports below 1024

sudo apt-get install authbind
# For port 80
sudo touch /etc/authbind/byport/80
sudo chmod 500 /etc/authbind/byport/80
sudo chown tomcat9.0 /etc/authbind/byport/80

# For port 443
sudo touch /etc/authbind/byport/443
sudo chmod 500 /etc/authbind/byport/443
sudo chown tomcat9.0 /etc/authbind/byport/443

echo 'AUTHBIND=yes' | sudo tee /usr/share/tomcat9.0/9.0.86/bin/setenv.sh
sudo chmod +x /usr/share/tomcat9.0/9.0.86/bin/setenv.sh

Here is my Tomcat9.0.service file:

[Unit]
 Description=Apache Tomcat Web Application Container
 After=network.target

 [Service]
 Type=forking
 PIDFile=/run/tomcat9.0/tomcat.pid
 Environment="JAVA_OPTS=-Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -Dserver -Dd64 -XX:+UseNUMA -Dlog4j2.formatMsgNoLookups=true -XX:+UseG1GC -Dfile.encoding=UTF-8 -Xms256M -Xmx512M -Djava.library.path=${CATALINA_BASE}/webapps/Thingworx/WEB-INF/extensions -DIGNITE_HOME=/usr/share/tomcat9.0/ignite"

I am not sure where to turn to, and I am looking for some assistance / guidance / suggestions / additional reading material.
Thanks.

Thanks, the issue was my certifacte in the end. I had not registered a domain to it and was trying to access. once I replaced my server.xml configs with standard port 8080 configs and no SSL encryption, it worked right away.

Thanks Rocko. I was able to find those trailing spaces and fix that error. Any idea why i am getting this:

Feb 20 16:13:39 ubuntu systemd[1]: Starting Apache Tomcat Web Application Container...

Update:
I have changed my config file to the following:

[Unit]
 Description=Apache Tomcat Web Application Container
 After=network.target

 [Service]
 User=tomcat9.0
 Group=tomcat9.0
 Type=forking
 PIDFile=/run/tomcat9.0/tomcat.pid

 [Install]

And now the service ran successfully for a minute. And then I get this error:

Any suggestions or comments?

Edit:
It the service seems to run in a somewhat stable state until I load the page and then it fails. Specifically when I load the Public IP of the server with out any further info on the link.

So when i try to navigate on my browser to https://xxx.xxx.xxx.xxx/Thingworx nothing happens but when i try to go to https://xx.xx.xx.xx the service stops running.

If /Thingworx isn't replying then the app wasn't deployed, so it's probably not a TWX problem (unless you can find TWX logs in the ThingworxStorage folder). Could be many things, so you can try to find other log files with more details and search Ubuntu and tomcat forums.

Also you added the User and Group setting to jsvc, so now you are running with a different user. Could it be that from your previous tries there are files, eg. pid files written and owned by a different user so tomcat9.0 user can't overwrite them?
