cesar-vermeulen opened a new issue, #33586:
URL: https://github.com/apache/airflow/issues/33586
### Apache Airflow version
2.7.0
### What happened
When connecting to the Airflow UI, we get the following message:
```
> Python version: 3.11.4
> Airflow version: 2.7.0
> Node: redact
>
-------------------------------------------------------------------------------
> Error! Please contact server admin.
```
If we investigate further and we look at the Kubernetes pod logs, we see
that following error message is thrown:

### What you think should happen instead
Show the Airflow UI
### How to reproduce
The deployment is done using the official Airflow helm chart with Azure AD
authentication on the webserver.
As soon as we did the upgrade to Airflow 2.7, the webserver became
unreacheable when trying to access it with the error shown above.
