Error: A plugin had an unrecoverable error. Will restart this plugin

Elastic Stack Logstash

I am running Elastick-Stack with Security on a single node successfully.
I am trying to send logs from another instance with Filebeat to Logstash (Elastic-Stack) without success and receive following 2 errors:

[ERROR][logstash.javapipeline ][test-pipe][mySpecialId_inp] A plugin had an unrecoverable error. Will restart this plugin.`

Does anyone have any idea what the reasons could be?

You have configured logstash to bind to an address that it is unable to resolve. What does your configuration look like?

Since it is a not uncommon mistake, let me mention that if you configure a beats input then the host option configures the address that the input listens on (0.0.0.0 by default) and does not specify the address of the remote beat that connects to it. Any address can connect.

Hi Badger,

you are my hero! I was already despairing.
I have changed the specific address in the beats input to 0.0.0.0 and it is running now :slight_smile: :ok_hand:
Thank you for your help and your fast response! :+1:
