HTTP error 400: Bad request

[jordimaggi]

Hi,
I am trying to use yagmail to send an email, when a long-running Jupyter cell finishes running on a Ubuntu 20.04 VM. It worked a few times last week. Now, however, all of a sudden, it throws this error:

---------------------------------------------------------------------------
