I recently upgraded to JG 0.5.1 and had to upgrade ElasticSearch as well. I upgraded ES to 6.8.6. Now, I'm not able to start JG. I'm running on Kubernetes and I've attached the log file as well. The error says it cannot connect to the URL for ES. I'm able to curl to that IP address and port and get a successful response. So I'm not sure what is going on. Any help is appreciated.

Thanks
