Sentry stopped displaying events in UI

I’ve installed Sentry on premise with just the default options. Everything was working fine until a couple of days ago. Somehow, no event are being added or created in the frontend.

I can see in the docker logs that events are coming in and stored, but I also see Kafka errors. I’ve recreated the sentry-kafka volume but this didn’t help. Any ideas how to get things up and running again? Below an except of the log:

Hi!

This seems to be the issue. Looks like you are having issues with your Kafka service.

  1. Delete stack via docker-compose down
  2. Delete Kafka volume’s _data content, except *. properties
  3. Run stack again: docker-compose up -d
