Hey @suminlim, It seems that Enterprise Search isn't able to access Elasticsearch using the host/username/password specified. You could try to SSH into the Enterprise Search docker container and attempt to issue a basic request to Elasticsearch in order to test/verify the connection. Something like: `curl -u [USERNAME]:[PASSWORD] https://[HOST AND PORT]/_cat/health` Let me know if that helps! Ross ---
