Unable to access tomcat server [RHEL]

I installed tomcat 8.033 on RHEL following the Thingworx 7.4 installation guide from the website. When running sudo systemctl status tomcat I get the following


â tomcat.service - Apache Tomcat Web Application Container

   Loaded: loaded (/usr/lib/systemd/system/tomcat.service; enabled; vendor preset: disabled)

However, I am still unable to access tomcat server from the browser.

Hi Muhammad Hassan,

Could you please verify the below steps:

  • Open the server.xml file located in tomcat install directory </usr/share/tomcat8/8.033/conf/server.xml>

  • Comment out or remove this section:

  • Paste the below contents directly below:

<Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="150" SSLEnabled="true" scheme="https" secure="true" keystoreFile="/usr/share/tomcat8/8.0.33/conf/.keystore" keystorePass="Enter keystorepassword" clientAuth="false" sslProtocol="TLS" />

  • Save the file and restart Tomcat.

If this doesn't resolve the issue please share the catalina.out file from Tomcat folder

I have tried your solution, however it still did not work. I looked at the catalina file and it might be a java related issue. However, I installed java as per the guide and rechecked my steps. I did not paste the whole log file since it is too long. Here is part of the log file
