Hi,
By default the CodeSite Dispatcher monitors the TCP and UDP ports. In an older version it was possible to toggle the Monitor Ports option in the Dispatcher Settings, but we removed that. However, the CSDispatcher.ini file still holds the setting for those who wish to turn it off.
Anyway, please check the C:\ProgramData\Raize\CodeSite\5.0\CSDispatcher.ini file and see if the MonitorPorts setting is turned off. If so, then simply set it to true and restart the Dispatcher.
