By changing network host you switched ES to run in Production mode. One of the bootstrap checks is failing. elastcsearch log will give more details on which check failed.

For list of checks see [Bootstrap Checks | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html)

You need to go through the list and check them all off, they are important to make sure your Elasticsearch is setup the best way possible.
