C2W4 restart_airflow not working

Hi there, I’m currently in C2W4 at the graded programming assignment “Building an Advanced Data Pipeline With Data Quality Checks”.

However the Airflow UI is inaccessible and when running bash ./scripts/restart_airflow.sh it keeps stuck in the loop waiting (~10 minutes already).

Any help would be appreciated!

Resolved by letting the AWS account expire (2h expiry) and restarting the lab.
