exception is occuring when elastic server is missing

Question

Below is the code for serilog elastic search.It's working perfectly when elastic service is running but fails when the server is not available

 .WriteTo.Elasticsearch(new ElasticsearchSinkOptions(new Uri("http://localhost:9200/")) // humio elastic bulk endpoint
                        {
                            AutoRegisterTemplate = true,
                            OverwriteTemplate = true,
                            DetectElasticsearchVersion = true,
                            AutoRegisterTemplateVersion = AutoRegisterTemplateVersion.ESv7,
                            NumberOfReplicas = 1,
                            NumberOfShards = 2,
                            RegisterTemplateFailure = RegisterTemplateRecovery.FailSink,
                            FailureCallback = e => Console.WriteLine("Unable to submit event " + e.MessageTemplate),
                            EmitEventFailure = EmitEventFailureHandling.WriteToSelfLog |
                                               EmitEventFailureHandling.WriteToFailureSink |
                                               EmitEventFailureHandling.RaiseCallback,
                            //FailureSink = new FileSink("./fail-{Date}.txt", new JsonFormatter(), null, null)
                            //ModifyConnectionSettings = x => x.BasicAuthentication(username: "", password: "88WS28JEuB0G2WC3cYufdgTINAxOGQvliBrqH5Vqutjb")  // password is ingest token from humio
                        })

Elasticsearch.Net.ElasticsearchClientException: 'No connection could be made because the target machine actively refused it.. Call: Status code unknown from: GET /_cat/nodes?h=v'

HttpRequestException: No connection could be made because the target machine actively refused it.
SocketException: No connection could be made because the target machine actively refused it.

This exception was originally thrown at this call stack:
System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(System.Threading.Tasks.Task)
System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(System.Threading.Tasks.Task)
System.Runtime.CompilerServices.ConfiguredTaskAwaitable.ConfiguredTaskAwaiter.GetResult()
System.Net.Http.ConnectHelper.ConnectAsync(string, int, System.Threading.CancellationToken)

sorry. I dont understand your question. It will throw an error if connection is not there. What are you expecting it to do? — Ashish Modi, Feb 12 '20 at 10:22
@AshishModi i would like to handle the exception when server is not found. so how can i handle exception when creating new uri — 11738472, Feb 17 '20 at 10:11
