I’ve been successfully running Metabase for the past 10 months. About a week ago the pulse emails stopped going out. It’s worth noting, when performing queries in metabase manually, things seemed to be working.
When explicitly pressing the Test Email, the email would go out, but it would not go out at the scheduled time.
After deleting new pulses, and trying to pinpoint what changes happened in our database, we decided to simply restart metabase:
sudo docker restart metabase
This did the trick and pulses were delivered after the fact. If this ever happens to anyone in the future, give restarting metabase a shot.
