Single overlord not leading

I installed all services in a single host, and I am facing issue that the overlord is not leading (thus causing infinite redirect in http://overlord-ip:8090/console.html)

[ec2-user@ip-10-0-0-57 druid]$ curl ip-10-0-0-57.ec2.internal:8090/druid/indexer/v1/isLeader


if it is not leading, who is leading?

[ec2-user@ip-10-0-0-57 druid]$ curl ip-10-0-0-57.ec2.internal:8090/druid/indexer/v1/leader


Same machine is leading…

Do you know how to workaround this?

I downloaded the druid from here:
