i am using prefect server on ubuntu machine

import prefect from prefect import task, Flow,Client @task def hello_task(): logger = prefect.context.get("logger") logger.info("Hello world!") with Flow("hello-flow") as flow: hello_task() state = flow.run() cl = Client() #cl.register(flow,project_name="pkc1") flow.register(project_name="pkc1")

this the script

grpahql page accessible

are you doing everything from the same machine? or is Server running on a VM and you access the UI from another machine? You need this config.toml addition on the machine from which you access the UI Also, how did you start your Server? You may need to add the --expose flag:

prefect server start --expose --use-volume

i am running prefect on server and accessing UI on local laptop via tunneling
