Tomcat Manager Application is running, but not accessible from Applications Manager
From tomcat v8 onwards, remote access to Manager Application is disabled by default. You can enable remote access by adding Applications Manager IP address in the RemoteAddrValve.
In the file, you can find the following keys:
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
Edit the above keys and include Applications Manager IP address under allow in the following format:
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|[Applications Manager IP ADDRESS]" />
Example :
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|192.29.28.20" />
where 192.29.28.20 is the IP address of Applications Manager machine.
Note : Restart Tomcat server after implementing the above changes.
If the issue still exists, reach out to our support with the screenshot of the error obtained to appmanager-support@manageengine.com along with the latest Support Information File (SIF) from Applications Manager with print all logs enabled for analysis.
