There is my configuration:

@i.m.superman hi there,
Are you running operate from the same environment where you are trying to access Elasticsearch?
Can you share the errors?

yes，same environment.
I acess Elasticsearch by curl and success.

@i.m.supermam I think that I’ve seen that problem before… can you try changing in the config file to

host: http://10.253.0.131

Instead of just the IP.
It is definitely a connection problem…

Why the indices are created if connection has problem ?

It is definitely a connection problem if you are getting unknown host exception in Java.

adding http:// didn’t help. Can you please share how are you running both Operate, Zeebe Cluster and ElasticSearch? Are you using Docker? I can see that you tried curling the host… so it might be a client issue. I can see people asking questions like this:

Which makes me think that the problem is that you are missing quotes around your IP address.
Look at my Kubernetes configuration here:

Can you try now "10.253.0.131" ?

Hope this helps.

Are you running this in Docker on Windows by any chance?

@jwulf
All Systems are Linux and there is no docker in my environment.
Only the IP configuration is working in operate-1.0.0.

@salaboy
Still not working with quotes.

I will try operate-1.0.0.
