Error 500 after period of inactivity

See original GitHub issue

Issue Summary

After a period of inactivity (in my case about a day or so) the database connection seems to be closed. When I visit the frontpage I get presented with an error 500 (see screenshot). I am using a docker deployment with mysql as the database technology.

To Reproduce

  1. Deploy the stackfile: docker stack deploy report --compose-file ./stack.yml
  2. Wait for a day (don’t visit the site)
  3. Visit the site and see the error 500

image My stack file:

version: '3.6'
