requests.exceptions.ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=3000)

I have installed pymiere_link
and I can see "Pymiere Link" in the extension of Window menu.
But when I run "print(pymiere.objects.app.isDocumentOpen())" in python shell, it shows these error:

The version of Premiere Pro is 14.4.0

Hi @xxxss ,
It seems the script cannot communicate with the panel in Premiere Pro. It may be because the port used by the pannel is already in use by another application (port 3000 on local url 127.0.0.1). Can you use the command netstat -ano | find "3000" and see if something appears?

Closed due to inactivity, let me know if you need to reopen it

Hello, I have the problem too.
netstat -ano | find "3000" command does not see the port, see:

Hello @yayayru ,
Do you see PymiereLink in Premiere Pro's Window>Extension menu ?
