This issue occurs when port 9089 and/or port 443 is open but is being used by another process or service. Be sure to close any non-essential Windows applications, services, and processes prior to using Converter.
To identify the service or process that is using port 9089 or 443:
-
-
To list all of the connections which are currently opened on the server, run the command:
netstat -ano
Look at the output list to identify the process that is listening on port 9089 and/or 443 (the last column displays the PID).
Note: You can redirect the output from above to a text file to search for the ports. For example:
netstat -ano > C:\<textfilename.txt>
-
Right-click on your Windows Task Bar and choose Task Manager.
-
Click the Processes tab.
-
To change the displayed columns, click View > Select Columns, selecting PID (Process Identifier), and click OK.
-
A PID displays in Task Manager. Look for the PID from step 3.
-
When you identify the process that is currently using port 9089 and/or 443, stop this process or service.
-
Retry the conversion.
Note: If other ports such as 443 and 9090 appear to be use by an application or appear to be closed, then follow the above steps to resolve. Just substitute port 9089 with the port number which is relevant to your specific instance.
