Re: [D] Airflow 3.0.6: "JWT token is not valid: Signature verification failed" when using SimpleAuthManager [airflow]

GitHub user bkarankar added a comment to the discussion: Airflow 3.0.6: "JWT token is not valid: Signature verification failed" when using SimpleAuthManager

JWT token is not valid: Signature verification failed typically indicates that different Airflow components are using different JWT signing secrets. In a multi-replica deployment (webserver/API server), verify that all pods share the same secret configuration and that no pods are running with stale environment variables after a secret change. Also check for rolling updates where old and new pods may be serving requests simultaneously. The repeated 403s after successful login are consistent with a token being issued by one instance and validated by another using a different signing key.

try the pre-configure script, make sure to change variables. https://github.com/bkarankar/Nexoryx_Airflow3
