Timeout

Hello,
Thank you for creating this project for getting notified. This works well on my laptop but when I try to get notified when my code runs on jupyter via email, this problem happened.

I turned my new backup google account' safety option off as instruction offered on https://pypi.org/project/knockknock/ but this happened and search on this issue has no results, so here it goes.

My recipants_emails is firstly set to my private email which is not of gmail, after error above occured, I changed it to my previous google account and this time keyrings.alt dependency is needed but enve if this is satisfied the error occured again. Now I'm helpless.
Can anyone explain why this happened and how can I solve it?
Much thanks!
