Hello. When I log in to datahub, error msg 'An unknown error occured (code 500)' occurs. To check what's wrong, I found that 'elasticsearch is not running' as the second figure shows. how to solve this?

Are you using quickstart ?

@gentle-hamburger-31302 yes, i am.

Try below steps • datahub docker nuke • docker container prune • docker volume prune • docker system prune • datahub docker quickstart --version v0.10.3
