Elasticsearch authentication warning

In some cases on when upgrading to elasticsearch 7.15+ you may have a similar warning on dashboard reloads/loads:

Warning: 299 Elasticsearch-7.15.0-79d65f6e357953a5b3cbcc5e2c7c21073d89aa29 "Elasticsearch built-in security features are not enabled. 
Without authentication, your cluster could be accessible to anyone. 
See https://www.elastic.co/guide/en/elasticsearch/reference/7.15/security-minimal-setup.html to enable security."

As any web access to SELKS goes via Scirius authentication a simple fix for can be:

1.) SSH into SELKS and edit /etc/elasticsearch/elasticsearch.yml
2.) Place the following line at the end of the file:
xpack.security.enabled: false
3.) Save the file and restart elasticsearch with:
systemctl restart elasticsearch
