Technical Details

what runs on :10055

The service uses TCP port 10055 for FLEXlm licensing traffic. FLEXlm clients contact a license manager to request licenses; the manager may coordinate with a vendor daemon on a separate port, which can be configured independently. The exact exchange and whether this endpoint is the manager or a vendor daemon depend on the Quantapoint deployment; it is not a general-purpose web service.
