Hey Team, i'm having an issue when running "prefect server create-tenant". I am getting the error [requests.exceptions.ReadTimeout: HTTPConnectionPool(host='localhost', port=4200): Read timed out. (read timeout=30)], however i have set the environment variable GRAPHQL_URL to my hostname where it's hosted; it seems not to be registering the env variable. Any advice on how to properly change the Graphql url?
