Manager app tomcat not accessible

Tomcat 403 Access Denied Error On Redhat

Tomcat 403 Access Denied, Sometimes. we want to access tomcat server over the network with Username and Password for doing some work via GUI. find process id tomcat using ps -ef | grep tomcat and kill tomcat service in Ubuntu using pkill -9 id tomcat. you can use tomcat service Linux to start the service, if tomcat not starting Linux, check the Catalina.out log for troubleshooting.

So it’s pretty simple you just have to define the username and password in tomcat-users.xml file on tomcat 9 server.

This issue will come when you will try to access Manager GUI of tomcat 9 Server. This issue will occur when you will try to access with particular IP address like I’m doing in this post.
