hi Prefect, I noticed that the

prefect/cli/server.py

shows user can specify different ports to start the Prefect server services (i.e. graphql_port='xxxx', server_port='xxxx', etc.). But when I used the flow.register(project_name) in my script, the

prefect/core/flow.py

seems like using default 4200 port to register the flow and had no param to adjust the registering port in

register()

function, so it raised HTTPConnection error. Once I changed line 1666 - flow.py

client = prefect.Client()

with

client = prefect.Client(api_server='<http://localhost>:MODIFIED_PORT/')

and it works. Is this an issue here? Thank you 🙂
