Hey, Not sure Graylog have version 7 out, looks like your service is having issues. Check your ` journalctl -xeu opensearch`. ---

Hey, > [@Sharzad](#): > > SERVICE\_UNAVAILABLE/1/state not recovered / initialized The journal logs you posted looks like the bottom half, you may need to scroll up. There should be a statement why it failed. EDIT: Also check the health of you indexer. ```auto curl -X GET “http://10.9.71.120:9200_cluster/health" ``` status should be green ```auto "status" : "green", ``` ---
