Failed to submit supervisor: Request failed with status code 502

I am getting Failed to submit supervisor: Request failed with status code 502 when I am submitting an ingestion spec using the unified console UI through the router in a 4 node cluster. The ingestion spec works when I am submitting it to a standalone installation when I am running Druid according to instructions of the tutorial.

The complete description is in the following StackOverflow link:

https://stackoverflow.com/questions/56220800/failed-to-submit-supervisor-request-failed-with-status-code-502-on-submitting

The logs don’t show any error.

What causes this error, and how can I further debug the problem?

Hi Nilayan,
Did you check Pivot logs, Overlord logs and middleManager logs? Any clues from any one of these 3 logs?

I am assuming that whatever s3 paths you mentioned for your deep storage and indexing are already created with proper permissions and ownerships.

Can you try by removing port 2181 from druid.zk.service.host and put only IP address?

Thanks,
