We are using elasticsearch 2.3 with head plugin and all was fine until the installation of shield.
Since shield is installed, the plugin head is broken and we cannot activate the contact button to have the cluster health.
Using the development tool from Chrome and inspecting the console, we notice that we have the message
GET http://ud0tx037:9200/_stats 403 (Forbidden)
Open this link gives the message:
{"error":{"root_cause":[{"type":"index_closed_exception","reason":"closed","index":"idx_eqx_bad_wasateperf-2017.07.01"}],"type":"index_closed_exception","reason":"closed","index":"idx_eqx_bad_wasateperf-2017.07.01"},"status":403}
It is correct that this indice is closed (we closed indices older than 5 days) but why is it fatal for head and what is the relationship with shield ?
thanks for your tips,
