i keep getting RuntimeError: Failed to reach API at http://127.0.0.1:4200 when i run my prefect flow. In my profiles.toml, i have set the PREFECT_API_URL. but i still keep getting the same error. I am currently using prefect==3.0.8

Hey Mike, Looks like a few of us have experienced this issue and have been able to see it fixed by restarting the server process. We're also potentially adding a fix in https://github.com/PrefectHQ/prefect/pull/15729

Thanks Dylan. I'd give it a try.
