Symptoms

  • NetWorker Web UI (NWUI) URL https://<FQDN>:9090/nwui  returns HTTP 404
  • All NWUI-related daemons are running
  • Port 9090 is listening
  • No warnings or errors appear in NWUI, AUTHC, or application monitoring logs
  •  Other AUTHC-based endpoints are accessible, for example:

Cause

The NWUI endpoint nwui and nwui.war  provided by the AUTHC Tomcat service, is missing from the /nsr/authc/webapps directory.

Resolution

Follow these steps to resolve the issue:

  • Copy the nwui.war file to the AUTHC webapps directory 
     cp /opt/nwui/lib/nwui.war /nsr/authc/webapps/ 
  • Check file permissions. If the file permissions are restricted (for example):
-rw------- 1 root root nwui.war
  • Update the permissions so the AUTHC Tomcat service can read and deploy the file:
chmod 755 /nsr/authc/webapps/nwui.war
  • Restart NetWorker service.
systemctl restart networker
  • Verify successful deployment. Confirm that the nwui directory is created under /nsr/authc/webapps with the following permissions:
drwx------.  4 nsrtomcat nsrtomcat       37 Dec 26 16:06 nwui
  • Access NWUI:
