Go and Check if a user is created or not if no please create a user by opening a file in /apache-tomcat-9.0.20/tomcat-users.xml add a line into it

<user username="tomcat" password="tomcat" roles="admin-gui,manager-gui,manager-script" />
Goto /apache-tomcat-9.0.20/webapps/manager/META-INF/ open context.xml comment everything in context tag example:

<Context antiResourceLocking="false" privileged="true" >
     <!--Valve className="org.apache.catalina.valves.RemoteAddrValve"
            allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" /-->
   </Context>

This may be work   Find the CATALINA HOME webapps manager META-INF context xml file and add the comment markers around the Valve    lt Context antiResourceLocking  false  privileged  true   gt    lt  --  lt Valve className  org apache catalina valves RemoteAddrValve  allow  127   d    d    d    1 0 0 0 0 0 0 0 1    gt  -- gt    lt  Context gt    You can find more details at this page

I have to modify the following files    CATALINA BASE conf Catalina localhost manager xml and add following line     lt Context privileged  true  antiResourceLocking  false        docBase    catalina home  webapps manager  gt           lt Valve className  org apache catalina valves RemoteAddrValve  allow          gt     lt  Context gt    This will allow tomcat to be accessed from any machine  if you want to grant access to specific IP then use the below value instead of allow              lt Valve className  org apache catalina valves RemoteAddrValve  allow  192  168  11  234    gt

fade s answer worked for me  I moved from 8 0 30 to 8 5 5 and the difference was the valve in  lt 8 0 30  manager META-INF context xml was already commented out from the tar file but was uncommented in 8 5 5 tar   I failed to read this important message in the 403 response      By default the Manager is only accessible from a browser running on   the same machine as Tomcat  If you wish to modify this restriction    you ll need to edit the Manager s context xml file    And failed to read this too      Since r1734267 a RemoteAddrValve is configured by default in Manager   and HostManager web applications  This feature is present in 9 0 0 M4   and 8 5 0 onwards    https   bz apache org bugzilla show bug cgi id 59672

I follwed the same tutorial but after some months I strangely got the error  403 Access Denied   while tryed to use Manager App  In this case I was using the ipaddress 8080 in the address bar and Tomcat Manager App didin t prompting for user password  In case of localhost 8080 the error was  401   the dialogbox asking for username and password was displayed but the user not recognized   I tried all the previous suggestions   solutions without lucky  The only way I found is been to repeat again the entire tutorial overwriting also the files   When finished  I  found again the old deployed project into the webapps directory  Now Apache Tomcat 8 5 16 Manager App are working again  I do not know what happened I didn t understand also because I m a newbie in Tomcat user

In my case it was the security constraints defined in web xml  Make sure they have the same roles you use in your tomcat-users xml file   For example  this is one of the out-of-the-box tags and will work with the standard tomcat-users xml     lt security-constraint gt       lt web-resource-collection gt         lt web-resource-name gt HTML Manager interface  for humans  lt  web-resource-name gt         lt url-pattern gt  html   lt  url-pattern gt       lt  web-resource-collection gt       lt auth-constraint gt          lt role-name gt manager-gui lt  role-name gt       lt  auth-constraint gt     lt  security-constraint gt    In my case an admin had used a different role-name which prevented me from accessing the manager

The solution that worked for me is edit context xml files in both  CATALINA HOME webapps manager META-INF and  CATALINA HOME webapps host-manager META-INF where my ip is 123 123 123 123    lt Context antiResourceLocking  false  privileged  true   gt     lt Valve className  org apache catalina valves RemoteAddrValve           allow  127   d    d    d    1 0 0 0 0 0 0 0 1 123 123 123 123    gt   lt  Context gt    I installed Tomcat 8 5 on Ubuntu and edited  CATALINA HOME conf tomcat-users xml    lt role rolename  admin-gui   gt   lt role rolename  manager-gui   gt   lt user username  myuser  password  mypass  roles  admin-gui manager-gui   gt    However  I still couldn t access both Tomcat Web Application Manager  localhost 8080 manager html  and Tomcat Virtual Host Manager  localhost 8080 host-manager html  until I edited context xml files

The correct answer is as  JaKu pointed out  Tomcat is confining the access to localhost to make it secure  This is as it should be  Port forwarding to tomcat is the correct thing to do  preferably under something secure like SSH

If non of above works for you  make sure tomcat has access to manager folder under webapps  chown       The message is the exact same message  and It took me 2 hours to figure out the problem   -   just for someone else who came here for the same issue as me
