Hi Team, Using saas Elastic service, Have been pushing logs from logstash to Elastic service setup but since yesterday the data is not being uploaded. Im seeing the following error in logstash log files. `Attempted to resurrect connection to dead ES instance, but got an error. {:url=>"https://elastic:xxxxxx@xxxxxxxxxxxxx.ap-northeast-1.aws.found.io:9243/", :error_type=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::HostUnreachableError, :error=>"Elasticsearch Unreachable: [https://elastic:xxxxxx@xxxxxxxxxx.ap-northeast-1.aws.found.io:9243/][Manticore::ResolutionFailure] xxxxxxxx.ap-northeast-1.aws.found.io"}` But i see the logs are being uploaded from other locations(of my organization). Please help in solving this. ---
