Control Panel, Full Text Search Not Working

[swt83]

My Full Text search page isn't loading in the Control Panel.

When I looked at /var/log/onlyoffice/web.api.log I saw this:

2021-02-03 20:10:47,147 ERROR [388] ASC.Api - method error: https://127.0.0.1/api/2.0/portal/search/state.json - Server error Elasticsearch.Net.ElasticsearchClientException: Error: ConnectFailure (Connection refused).

Any ideas how to fix?

Please check systemctl status elasticsearch and /var/log/onlyoffice/Index/elasticsearch.log for errors. Make sure you have enought RAM (8gb+ recommended).

Also check systemctl status onlyofficeIndex and it's log for errors. Try to restart it. Run this curl http://localhost:9200/_cat/indices.
