Run / cmd / netstat -aon | find "port"
If there is nothing in the list, no program is running on that port.
If there is something in the list it will also show in Task manager. If you add PID you can see all ids that are being used and what program are running it.
For example if you are using radio via your browser and Skype, that can interfere with Consignor.
One of Consignor's ports is used by another program
