How to change the Web Server port used by Mobile Device Manager Plus?

This guide explains how to change the HTTP/HTTPS port used by the Mobile Device Manager Plus server for agent communication and web console access. Administrators stop the server, edit the http.port and https.port values in websettings.conf, then restart the service and reconnect using the new port numbers. Changing the port unmanages all enrolled devices, which must then be re-enrolled, so this change is recommended only when necessary.

Description

By default, the Mobile Device Manager Plus server uses http port 9020 or https port 9383 to complete the following tasks:

  • Enable agent-server communication
  • Access the Web client

This port is chosen during the installation of the Mobile Device Manager Plus server. You can change the port number after installation, if required.

Warning!
