The second Ansoft licence port, and today the Tomcat port for the ANSYS License Management Center web UI.
1084 was registered alongside 1083 as the second port of the Ansoft (now ANSYS) licence manager. In current ANSYS installations it has a live second life: the licence-manager installer configures a bundled Tomcat on port 1084 to serve the browser-based License Management Center, which admins open at http://localhost:1084/. It is bound to the licence server itself by default, and installs log an explicit check that 1084 is free before starting Tomcat.
Do not expose
It is a licence-administration web console shipped on an embedded Tomcat. Leave it local to the licence server, or reach it over a VPN — do not publish it to get remote admin access.
