I would prefer to block this at the web server level. However, I have now added a maximum app container lifetime through the middleware. The previous system supposedly only removed containers
of users that left the site. The new system also removes actively used containers. Let us see how well that works. If that is insufficient, I will set up the mentioned cron job.
Following tonight’s update, the app should work again.

It's what you expect from a bot.
