Druid take 504 Error while I try to upload my data from kafka server

I’m beginner using kafka and druid. At this time, I want to upload my data to druid from kafka server. At the first time, it was successful to upload any data. Recently I open the configuration of both (kafka and druid) but I didn’t change anything, just open the file to see the config. At this time I have a problem with druid when I try to upload my data from kafka server at ‘parse data’ step it get 504 error that the timeout and getting so long to wait the loading in druid.

the detail is here apache zookeeper - Druid take 504 Error while I try to upload my data from kafka server - Stack Overflow because i dont have permission to upload any picture

I hope, I have a solution. Thank in advanced

Hey @handrimaulud - I’d suggest checking the health of your processes to check that they are running OK and especially that your Zookeeper is running OK. Try doing a check for errors in the individual process logs? I would focus on the coordinator, overlord, router, broker, and middlemanager processes.

OOI, when you reconnected, did you see the preview of the data OK?
