> Reporter: Max Richter

> Hello,
> I am running Airflow 1.9.0 successfully with a localhost MySQL database,
> version 5.7.23.
> I switched sql_alchemy_conn =
> mysql://airflow:<password>@<remote-host>:3306/airflow in order to use the
> proper MySQL server - same version 5.7.23.
> I created a dump from my local instance to the remote one.
> Issue:
> * When tasks are executed by the scheduler everything runs fine, tasks are
> executed and DB updated
> * When manually triggering a task via the webserver, I am getting
> "_pickle.UnpicklingError" please see error__log.txt for full log
> In the end, I only changed this one line in airflow.cfg which is causing that
> I can not use it with a remote MySQL server.
>
> Best,
> Max
