Updated web-server and now website providing 503

Question

To start with I'm not familiar with web-page hosting Apache/tomcat. I recently updated a private web-server in what may have been the first time in a long time using yum, and now the website is not working. I can go to the https://$server/ page and I get the normal page saying it will redirect to another page, or click to redirect. This brings me to a https://$server//iweb/servlet/menu?opt=menu page with a 503 error. This use to be a page with a log-in prompt.

My current assumption is that the java servlet hasn't started. I haven't found any blogs that could help me, but that could be due to my unfamiliarity with the server and web-server architecture in general. Any next steps in getting the menue page working, even just pointing to the correct logs to review, would he helpful.

After the update from 2.2.22 to 2.2.3 I made the following changes to get the httpd service to start

• remap /etc/httpd/modulas to /usr/lib64/httpd/modules
• remap /ect/http/logs to /usr/lib64/https/logs
• edit /etc/httpd/conf.d/certs.conf to include LoadModule ssl_module & Listen 443
• edit /etc/httpd/conf.d/ssl.conf to remove Listen 443
• remap /etc/httpd/run to /var/run

UPDATE 1 Left out of the original post I also modified the server.xml to remove the "Ghostcat" (CVE-2020-1938) vulnerability <!--<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />-->

I also found that the servilet is running, but you need to go to the tomcat 8080 port server:8080/iweb/servlet/menu?opt=menu
