Switching a data node from secure to insecure needs Graylog restart

[mpfz0r]

If I change a datanode to run with insecure_startup=true

Graylog keeps trying to use TLS until I restart it:

2024-04-11T20:44:39.585Z ERROR [VersionProbe] Unable to retrieve version from Elasticsearch node: Unsupported or unrecognized SSL message. - Unsupported or unrecognized SSL message.
2024-04-11T20:44:39.586Z INFO  [VersionProbe] OpenSearch/Elasticsearch is not available. Retry #26
2024-04-11T20:44:40.052Z WARN  [Messages] Caught exception during bulk indexing: ElasticsearchException{message=OpenSearchException[An error occurred: ]; nested: IOException[Unrecognized SSL message, plai
ntext connection?]; nested: SSLException[Unrecognized SSL message, plaintext connection?];, errorDetails=[]}, retrying (attempt #18).

Ideally the VersionProbe would know that the DataNode got reconfigured.

Your Environment

• Graylog Version: 6.0.0.rc2
