At the upper-right, I see the Warning that you are in Coordinator mode.

Please check that all your processes can see one another. I usually start with Zookeeper…

Found the solution, in the coordinator.log there was warning log:

2022-01-25 08:00:05,229 WARN org.apache.druid.server.http.DataSourcesResource: datasource not found [liveedu_exception_json]

I simply delete all segements from druid.druid_segments table with dataSource = ‘liveedu_exception_json’ , and it worked.
