I have an application using ElasticSearch. Application worked for about year until last week.
Now I have an error:

Application is .NET application and uses Nest library for ElasticSearch communication:
Connection is established using following statements:
connectionPool = new StaticConnectionPool(new Uri { new Uri(String.Format("http://{0}:{1}", ELASTIC_SEARCH_SERVER, ELASTIC_SEARCH_PORT)) });
connectionSettings = new ConnectionSettings(connectionPool);
elasticClient = new ElasticClient(connectionSettings);
No changes where made lately in elasticsearch module, which suggests that problems occurred due to changes in network configuration???
I developed a console application for debug purposes. The code in console application is as much as possible like in web application, but it works.
I'm very gratefull for any suggestions that could point me to a solution
