how did you upgrade?

Did you consider the upgrade to the latest stable Elasticsearch 5.6 release?

Be a little more verbose on details of your setup and somebody might help.

Hi Jan,

I found error cause of enable option “elasticsearch_discovery_filter = rack:42”. I disabled it, then It worked.
And should I upgrade elasticsearch v5.5 t v5.6?

Yes, I would recommend upgrading to the latest stable version of Elasticsearch in the 5.x branch.
