"connection refused" is an indication that there is no (running)
server at the connection port.

Unlike simple web servers, more complex web frameworks are often not
started automatically at system startup (as they require complex
configuration to be meaningfully usable). Likely, this your
case: you likely need to explicitely start the server component.

Likely, the code above is supposed to start the server component.
Ensure, that the start is successful (I typically use "lsof -i"
to find out whether a server is listening on the expected port).
