I’ve found that ui-port might be a cause.
Commands what I’ve done on the terminals are follows.
OS: ubuntu 18.04
python: 3.8.13
After creating a project named
tutorialprefect server start --ui-port 2222prefect agent local startpython flow.pyimport prefect
from prefect import task, Flow
@task
def say_hello():
logger = prefect.context.get("logger")
<http://logger.info|logger.info>("Hello, Cloud!")
with Flow("hello-flow") as flow:
say_hello()
# Register the flow under the "tutorial" project
flow.register(project_name="tutorial")Flow URL: <http://localhost:8080/default/flow/ebf8a573-403a-4928-96ea-098dd1d5ca93>

04/08/2022, 5:59 AMOk so the terminal 3 message pulls the UI URL in this line, which pulls it from the config.toml so you should need to change this to match the 2222.
What does your config.toml look like?
I think you should still be able to access the UI though
I expect at least one of
<http://localhost:8080><http://localhost:2222>I also didn’t know you were on server when you first posted. Just want to make sure you know Prefect Cloud is a lot easier to get started with because we host all the services and the free tier has 20k task runs per month.
