I have an Apache Airflow v2.2.0 instance running on a linux server. When I create a new dag I can see it listed with 'airflow dags list' but it doesn't show up in the web user interface.
I tried also to take out and bring back an existing dag with the same result: the dag is listed from console but doesn't load anymore to the Web UI.
did anyone ever experience something similar?
restarting the scheduler solved the issue
