Elasticsearch license.expired.feature security status 403

Question

I am using below code

var settings = new ConnectionSettings(new Uri("https://10.8.173.179:9200"));
                    settings.BasicAuthentication("elastic", "password"); 
                    settings.ServerCertificateValidationCallback(CertificateValidations.AllowAll);
                    var lowlevelClient = new ElasticLowLevelClient(settings);
                    var health = lowlevelClient.Cluster.Health<StringResponse>().DebugInformation;

Getting : "security","suppressed":[{"type":"security_exception","reason":"current license is non-compliant for [security]","license.expired.feature":"security"}]},"status":403}

Answer 1

It sounds like you may have been using a trial license. You can check which license you are running with by using the Get License API

var client = new ElasticLowLevelClient();

var getLicenseResponse = client.License.Get<StringResponse>();

which will issue the request

GET http://localhost:9200/_license

If the "type" is "trial" in the returned response, you are using a trial license.

You can revert to using a free basic license. If you're running

• a 6.x version greater or equal to 6.8.0
• a 7.x version greater or equal to 7.1.0

Core security features such as TLS, basic and native realm and role-based access control can be used with the basic license..

To start the basic license, you can use the Start Basic License API

var startBasicResponse = client.License.StartBasic<StringResponse>();

which sends a request to

POST http://localhost:9200/_license/start_basic

NOTE As per the API documentation, you must submit the API request with the acknowledge parameter set to "true" for the changes to take effect; you can submit the API call first without setting this parameter, to understand what changes it makes it terms of access to features.
