2183091 - When Tomcat manager is opened using browser url getting Http://servername:port/manager/html -HTTP Status 404 /manager/html

• When clicked on Tomcat Manager in Tomcat's homepage ie., http://localhost:8080/, it shows HTTP Status 404 - /manager/html. Previously it worked fine. The username and password for tomcat manager is present in tomcat-users.xml file and are correctly edited.
• Tomcat-users.xml was correctly configured for authentication. Below is the working sample configuration of tomcat-users.xml (admin-gui is role to a user named tomcat with a password of Password1)

<tomcat-users>
<role rolename="tomcat"/>
<role rolename="admin"/>
<role rolename="operator"/>
<role rolename="manager"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="Password1" roles="admin-gui,tomcat,manager"/>
<user username="admin" password="nopasswordforyou" roles="admin,tomcat,manager"/>
<user username="operator" password="nevermind" roles="operator"/>
</tomcat-users>
