> I just started using the base_url to put the webserver behind nginx proxy

> I've tried following the docs for nginx proxy, i.e.
> [webserver]
> base_url = [http://localhost/airflow|http://airflow-web/airflow]
>
> I've also tried setting the base_url to the fully-qualified endpoint:
> base_url = [https://example.com/airflow|https://domain.com/airflow]
>
> Neither work, both give the TypeError exception.
>
> If I remove the sub-path:
> base_url = [https://example.com|https://domain.com/]
> then the app starts and runs ok and i can access it on the host but not
> through the proxy.
