I have recently encountered my Cloud Composer service to be inaccessible with the error message saying: This site can't be reached. 'xx' server IP address could not be found. Yet, the DAGs are still running successfully.
I have not made any changes to this service and have already checked whether airflow.cfg has been deleted.
It seems that there are few resources regarding this. I have also tried some recommendations from the resources I found to no avail. Hoping for some help with this.
