When I want to see the origin airflow address from the datahub, I press the button “View in Airflow” as shown above. But the url turns to the http://localhost:8080/taskinstance/list/?flt1_dag_id_equals=auto_airflow_test3&_flt_3_task_id=task_b. How could i change the default localhost to certain ip like 192.168.1.2?

you should set

base_url

in your airflow config -> https://airflow.apache.org/docs/apache-airflow/stable/configurations-ref.html#base-url
