Issue with Elastic search

We are in the midle of installing Elastic search and kibana for installing RPA Orchestrator but after installing elastic search I am seeing that service is getting stopped.

Please find below details and help me in fixing the issue asap.

Hi @loginerror ,

Is there any timeframe on when support for ELK version 7.x will be available? Will it be in the next enterprise release?

Is there a workaround to make this work?
