When I run the following in my Jupyter Notebook:

tr.set_app_key('xxxxxxxxxxxxxxxxxxxxxxxxxxxx375eacd87e24')

I get the following error message:

Error on checking port 9000 : HTTPConnectionPool(host='localhost', port=9000): Max retries exceeded with url: /api/v1/data (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x000001F70A2CF0F0>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it',)) Error on checking port 9000 : HTTPConnectionPool(host='localhost', port=9000): Max retries exceeded with url: /api/v1/data (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x000001F70A2CF4E0>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it',)) Error on checking port 36036 : HTTPConnectionPool(host='localhost', port=36036): Max retries exceeded with url: /api/v1/data (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x000001F70A2CF7B8>: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it',)) Error on handshake port None : Failed to parse: localhost:None Port number was not identified. Check if Eikon Desktop or Eikon API Proxy is running.

However my Eikon Desktop is running at the same time.

Please would someone help me to resolve this issue? I don't have much experience programming. Thanks
