With Grafana v4.02 running on RHEL 6.6 I am unable to add a Datasource to a new Gralog ElasticSearch Cluster which is a cluster.
I have an existing datasource to our Legacy Graylog host (not clustered) which works, however this is not behind a LoadBalancer. I have enabled debug logging for Grafana and when reproducing the problem (simply entering the https://loadbalncedIP:9000 and attempting to save the configuration and wild card for the index) i get in the console “ERROR”. However this does not report any thing in the logs.
If I attempt the connection to a single node on port 9000 (which is available tested with telnet). I do get a Info level error only reporting a 502 in the message.
Any thoughts as to why i get ERROR only and no other debug level information.
