Troubleshoot Tomcat

due to the good experience from our last project I would like to ask you if you can take a look at my Tomcat server. Although I haven't made any changes to the server in the last weeks, Tomcat suddenly doesn't work properly anymore. Among other things, the following error message appears in the log files: 04-Aug-2023 07:48:19.049 SCHWERWIEGEND [main] org.apache.catalina.util.LifecycleBase.handleSubClassException Failed to initialize component [Connector[HTTP/1.1-8080]]

Maybe you can take a look at the problems and give me an estimate of what is causing them and what effort is required to solve them. Are you interested?

Regards,
Ulrich
