403 Problem solving for Tomcat Manager

after running Tomcat, enter http://localhost:8080/ , click Tomcat Manager, and after entering username and password, there is a 403 error.

Workaround:

Check the Tomcat installation directory,

(1) \conf\tomcat-users.xml

<?xml version= ' 1.0 ' encoding= ' utf-8 '?>
<tomcat-users>
<role rolename= "Manager"/>
<role rolename= "admin"/>
<user username= "admin" password= "123" roles= "Admin,manager"/>
</tomcat-users>

(2) \webapps\manager\web-inf\web.xml

<auth-constraint>
<role-name>manager</role-name>
</auth-constraint>

Make sure that the name of role in Tomcat-users.xml and Web. XML corresponds.
