Did you start the unoserver first? Otherwise you will get an error there: ConnectionRefusedError: [Errno 111] Connection refused

1. start first command "unoserver &"
2. try convert command "unoconvert convert-to pdf {targetFile} {resultFile}
3. got an error message

when I kill all processes related to unoserver and try again, it works. But I don't know the difference between it working and not working. I'm trying to start unoserver as a background process all the time. So I'm running it with a & after the command. What should I do?

[regebro]

Try opening unoserver in a separate terminal and see what output it gives you, maybe it shows some error message after a while?
