Hi @snalaband,

Welcome to the community! Can you check your logstash configuration? It looks like you're getting an unauthorized error. I would have a look at [this thread](https://discuss.elastic.co/t/logstash-badresponsecodeerror-message-got-response-code-401/299780) for example configuration that should solve the issue.
